The present invention relates to a self-moving gardening robot and a system thereof. The present invention particularly relates to a self-moving gardening robot and a system thereof for implementing a courtyard maintenance function.
A common home courtyard scenario is shown in
To release users from various types of courtyard maintenance tasks, various automatic and semi-automatic courtyard maintenance machines have emerged on the market, for example, an automatic robotic lawn mower configured to cut grasses, a semi-automatic blowing and sucking machine configured to sweep fallen leaves, various types of automatic irrigation systems configured to spray water, a semi-automatic sowing machine configured to sow, a semi-automatic fertilizing machine configured to fertilize, a semi-automatic soil loosening machine configured to loosen soil, and a weeding machine configured to remove withered grasses.
To finish all courtyard maintenance work, a user needs to buy various machines for performing different tasks. In this way, first the costs are high and second the home environment may be caused to be in disorder.
Further, by merely using a self-moving gardening robot for implementing a single functional task of courtyard maintenance, the user needs to select different functional machines at different times and to control on and off the different functional machines when performing courtyard maintenance. The degree of human intervention is excessively high and robotic courtyard maintenance cannot be well implemented.
Therefore, the user is in urgent need of a self-moving gardening robot platform when performing courtyard maintenance. The self-moving machine platform can be integrated with a plurality of functions of courtyard maintenance.
In an existing self-moving gardening robot system, a charging station and related circuits need to be arranged for each automatic apparatus separately. A user needs to arrange different boundary signal lines for different systems, and mutual interference may be generated between the boundary signal lines.
In an existing self-moving gardening robot for implementing a single functional task of courtyard maintenance, the self-moving gardening robot merely performs a functional task on a whole lawn according to an instruction. A correspondingly rising problem is that the task may still be mechanically performed in some areas of the courtyard in which the task does not need to be performed, and a same functional task may be repeatedly performed in some areas of the lawn.
In the existing self-moving gardening robot for implementing a single functional task of lawn maintenance, for example, in a self-moving gardening robot for fertilizing, a user needs to replenish a fertilizer in real time when the fertilizer carried by the self-moving machine is used up. The self-moving gardening robot for fertilizing lacks full automation and is not advantageous in user experience.
In the existing self-moving gardening robot for implementing a single functional task of lawn maintenance, although a user can remotely control the self-moving gardening robot, a supplier or service provider of the self-moving gardening robot does not implement working condition counting and simple management and control function of the self-moving gardening robot by using a remote facility.
At present, to resolve a lawn irrigation problem in a courtyard, a user usually uses an automatic irrigation system with embedded pipes or performs irrigation manually. By using an automatic irrigation system with embedded pipes, laying of the pipes not only causes damage to the lawn surface, but also costs labor and money. By performing irrigation manually, the user cannot be released from the courtyard maintenance tasks. Therefore, an automatic water spraying machine not needing embedded pipes is needed urgently to resolve the lawn irrigation problem.
In view of the above, an objective of the present invention lies in providing a self-moving gardening robot having a positioning function, capable of working and traveling along a planned path, and integrated with multiple functions.

The provider or manufacturer of the self-moving gardening robot 100 may also automatically update a software version in the self-moving gardening robot 100 through the service end 300 or automatically update a working schedule of the self-moving gardening robot 100 based on database information.
In another embodiment, the self-moving gardening robot 100 may alternatively perform remote communications with the user equipment 200 through the wireless communication module 90. The service end 300 then performs remote communications with the user equipment 200. The service end 300 collects and counts data of the self-moving gardening robot 100 through the user equipment 200 or/and sends various prompt instructions to the user equipment 200. Certainly, in some cases, a remote working system of the self-moving gardening robot 100 may not include a service end 300.
In an embodiment, the working module 50 is an execution component performing a single function and correspondingly, the self-moving gardening robot 100 is a single functional self-moving gardening robot. In this embodiment, the self-moving gardening robot 100 has different functions based on different working modules 50. Specifically, when the working module 50 is a cutting component, the self-moving gardening robot 100 is an automatic lawn mower; when the working module 50 is a sweeping component, the self-moving gardening robot 100 is an automatic sweeper (a robotic vacuum cleaner or a robotic snow sweeper); when the working module 50 is a fertilizing component, the self-moving gardening robot 100 is an automatic fertilizing machine; and when the working module 50 is a water spraying component, the self-moving gardening robot 100 is an automatic water spraying machine, or the like.

In this embodiment, the self-moving gardening robot 100 further includes a material cavity 52, configured to store materials such as seeds, a fertilizer, water, and pesticides. Specifically, the material cavity 52 is fixedly provided in the housing 10. The material cavity 52 is provided with a material inlet 521, and a material enters the material cavity 52 through the material inlet 521. The material cavity 52 is provided with a material outlet 523 (that is, a material opening), and a material falls on a lawn through the material outlet 523, thereby implementing functions such as sowing, fertilizing, water spraying, and pesticides spraying. The material inlet 521 is provided with an inlet cap configured to cover the inlet. The inlet cap is externally connected to an elastic member and automatically covers the inlet under an elastic force of the elastic member. When an external force is applied to the inlet cap, the external force overcomes the elastic force of the elastic member, the inlet cap no longer covers the inlet, and the material enters the material cavity 52 from the inlet. The material outlet 523 includes an outlet cap configured to cover the outlet. The outlet cap is driven by the power module 80 and may automatically cover the outlet or not cover the outlet in a connection manner. The outlet cap is equivalent to an automatic valve (a type of automatic switch). In one of embodiments, the inlet cap of the material inlet 521 is also configured as an automatic valve. Under control of the control module 30, the automatic valves can automatically open and close the inlet cap and the outlet cap. In one of embodiments, under control of the control module 30, the automatic valves can control an opening size of the inlet cap and/or the outlet cap, to further control a flow of the material. In one of embodiments, based on different types of materials, the control module 30 controls a travel speed and an opening size of the outlet cap of the self-moving gardening robot 100, thereby satisfying an amount of a material needed in each square meter of a lawn. In this embodiment, there is one material inlet, located on an upper surface of the housing 10 at a position opposite to the material cavity 52. There is one material outlet, located on a lower surface of the housing 10 at a position opposite to the material cavity 52. In one of embodiments, the material inlet 521 is disposed in a front side of the material cavity 52 and the material outlet 523 is disposed in a back side of the material cavity 52. Certainly, the numbers of the material inlets and the material outlets may alternatively be other numbers.
In one of embodiments, the material cavity may be provided with a plurality of outlets. The different material outlets are configured to release materials of different functions or in different forms. In this embodiment, the opening sizes of the different material outlets may also be set to be different.
In one of embodiments, the self-moving gardening robot 100 further includes a capacity detection device 524 configured to detect a material storage capacity. The capacity detection device 524 is electrically connected to the control module 30. The capacity detection device 524 detects a residual material capacity in the material cavity 52 and transmits the capacity signal to the control module 30. The control module 30 controls, based on different capacity signals, the self-moving gardening robot 100 to perform different actions. There may be a plurality of implementations of the capacity detection device 524, for example, a ranging sensor, a weight sensor, a space sensor, a capacitance detection sensor, or a Hall induction sensor. When a main function of the material cavity 52 is storing a liquid, the capacity detection device 524 may alternatively use a float to perform capacity detection. In a ranging sensor, specifically an infrared sensor, an ultrasonic sensor, a laser sensor, or the like may be used.
In a specific embodiment, the capacity detection device 524 uses a ranging sensor. In one of embodiments, the ranging sensor is disposed on an upper surface of a cavity body of the material cavity 52. The ranging sensor is close to the material inlet 521 of the material cavity 52 and substantially faces toward the material outlet 523. The ranging sensor transmits a ranging signal. The ranging signal contacts a surface of the material and is then reflected back to the ranging sensor. The control module 30 determines, according to a time difference between transmitted ranging signal and received ranging signal by the ranging sensor, a position of a material upper surface in the material cavity 52, to further determine a residual material in the material cavity 52. When the self-moving gardening robot 100 travels on a slope, the material in the material cavity 52 moves toward a slope toe due to a gravity action, resulting in that the material surface presents an inclined shape. Therefore, the residual capacity detected by one capacity detection device 524 is no longer accurate. In one of embodiments, the control module 30 is provided with a capacity conversion unit 302. The capacity conversion unit 302 scales, according to a slope gradient of a slope and based on a preset algorithm, the capacity detected by the capacity detection device 524. Through conversion of the capacity conversion unit 302, the self-moving gardening robot 10 may not be incapable of accurately determining a residual material capacity in the material cavity 52 due to be travelling on the slope.
Optionally, the self-moving gardening robot 100 is provided with a plurality of capacity detection devices 524. In an embodiment, the self-moving gardening robot 100 is provided with two capacity detection devices 524. The two capacity detection devices 524 are arranged at an interval along an axis of a travelling direction of the self-moving gardening robot 100. When the self-moving gardening robot 100 travels on a slope, the control module 30 respectively receive results detected by the two capacity detection devices 524. The two detected results are added and averaged and a result obtained after adding and averaging is used as the residual material capacity in the material cavity 52. In this embodiment, the two capacity detection devices 524 are arranged at an interval along an axis of a travelling direction of the self-moving gardening robot 100. When the self-moving gardening robot 100 is on a slope, the two capacity detection devices 524 respectively detect capacity values at locations of the capacity detection devices 524. The two capacity values are added and averaged to eliminate or reduce impact of material incline on the detected result.

In another embodiment, a front end of the housing 10 of the self-moving gardening robot 100 is provided with a counter weight. By disposing the counter weight at the front end of the housing 10, an offset of the center of gravity of the whole machine of the self-moving gardening robot 100 due to incline of the materials in the material cavity in the climbing process is effectively balanced.
In another embodiment, the material cavity 52 further has a self-cleaning function. A cleaning device is disposed in the material cavity 52. The cleaning device may automatically and regularly clean the material cavity or be started by a user to clean the material cavity.
In another embodiment, the self-moving gardening robot 100 may alternatively use a drag box to store a material. As shown in
In an embodiment, the material cavity 52 is disposed at a predetermined space of the self-moving gardening robot 100. Some elements apt to generate heat, such as the energy module 60 and the control module 30, in the working process of the self-moving gardening robot 100 are arranged in peripheries of the material cavity 52. When water is stored in the material cavity 52, the water may cool the peripheries of the material cavity, so as to cool the energy module 60 and the control module 30. In one of embodiments, the cavity body of the material cavity 52 is at least partially made of a thermal conductive material.
A volume capacity of the material cavity 52 is a significant parameter in design of the self-moving gardening robot 100. A size of the volume capacity of the material cavity 52 may affect a specific working efficiency of the self-moving gardening robot 100 and whether the self-moving gardening robot 100 causes damage to a lawn when performing a work. When designing the volume capacity of the material cavity 52, specific factors to be considered include: a size of a working area of the self-moving gardening robot 100, a travel speed of the self-moving gardening robot 100 during work, a total amount of working time of the self-moving gardening robot 100 per unit area, a plant transpiration amount associated with a local climate, an amount of precipitation associated with the local climate, a speed at which water is injected into the material cavity 52 each time, and a water spraying speed of the self-moving gardening robot 100. Among the foregoing contributory factors, the volume capacity of the material cavity 52 is in positive proportion to the working area and the plant transpiration amount. That is, a larger working area and plant transpiration amount indicates a larger volume capacity of the material cavity 52 needed. Among the foregoing contributory factors, the volume capacity of the material cavity 52 is in negative proportion to the travel speed, a working duration, an amount of precipitation, a water injection speed, and a water spraying speed. A larger travel speed of the self-moving gardening robot 100 during working, total amount of working time of the self-moving gardening robot 100 per unit area, amount of precipitation, speed at which water is injected into the material cavity 52 each time, and water spraying speed of the self-moving gardening robot 100 indicates a smaller volume of the material cavity 52 to be designed on the contrary.
In one of embodiments, when implementing functions such as sowing, fertilizing, water spraying, and pesticides spraying, the self-moving gardening robot 100 may use a rotation action of the cutting module 56, to achieve the purposes such as no material stack and even dispersion. When implementing the functions such as sowing, fertilizing, water spraying, and pesticides spraying, the control module 30 controls the cutting module 56 to rotate at a low speed. Materials such as seeds, a fertilizer, water, and pesticides flowing out from the material outlet first fall on an upper surface part of the cutting module 56 and are sprayed and spread to a lawn under the rotation action of the cutting module 56.
In one of embodiments, the control module 30 includes a rotation speed control unit.
When the self-moving gardening robot 100 performs different functions such as grass cutting, water spraying, sowing, pesticides spraying, and fertilizing, the rotation speed control unit controls the cutting module 56 to rotate at different speeds. When the self-moving gardening robot 100 performs a grass cutting function, the rotation speed control unit controls the cutting module 56 to rotate at a high speed. The rotation speed is greater than 2000 r/min, In one of embodiments, 2100 r/min or 2800 r/min. When the self-moving gardening robot 100 performs material functions such as water spraying, sowing, pesticides spraying, and fertilizing, the rotation speed control unit controls the cutting module 56 to rotate at a low speed. The rotation speed is less than 1000 r/min. In one of embodiments, when performing different material functions, the rotation speed control unit may also control the rotation speed of the cutting module 56 to be different correspondingly. Specifically, according to factors such as a weight/volume of a material needed per square meters, and a travel speed and machine body area of the self-moving gardening robot 100, the rotation speed of the cutting module 56 is controlled to be different. As known by those skilled in the art, the control module 30 herein not only includes a program control method such as a micro processor, but also includes a control circuit method of electronic circuit design.
In one of embodiments, the bottom of the material cavity 52 of the self-moving gardening robot 100 is provided with a drip irrigation device. The drip irrigation device is connected to the material cavity 52.

When implementing the soil loosening function, the mating part 542 of the second soil loosening accessory 54b matches the multi-functional accessory interface 12 of the self-moving gardening robot 100. The self-moving gardening robot 100 moves automatically in the working area, to drive the roller part 548 to move on the working surface. In the moving process of the roller 548, the protrusions 546 are partially inserted into the working surface, to flip over mud of the working surface, thereby implementing the soil loosening function.
The working principle of implementing the withered grass removing function by the self-moving gardening robot is similar to that of implementing the soil loosening function. Therefore, a mechanical structure of a withered grass removing accessory may be referred to the mechanical structure of the soil loosening accessory. The withered grass removing accessory is not described in detail again herein.
When implementing the fallen leaves collecting function, the mating part 542 of the fallen leaves sucking accessory 54c matches the multi-functional accessory interface 12 of the self-moving gardening robot 100. The self-moving gardening robot 100 automatically moves in the working area, and the fallen leaves collecting part 5433 is started at the same time. The fallen leaves collecting part 5433 collects fallen leaves on a path through which the self-moving gardening robot 100 passes to the fallen leaves storage part 5431. When the full storage detection device shows that the fallen leaves storage part 5431 is full, the fallen leaves collecting part 5433 stops working. The self-moving gardening robot 100 records the breakpoint location, moves to a preset fallen leaves storage point, and discharges the fallen leaves. In one of embodiments, the self-moving gardening robot 100 is provided with a path planning unit, so that the self-moving gardening robot 100 moves in an optimal path for collecting fallen leaves or returning to the breakpoint location.
In this embodiment, the path planning unit stores a preset path mode, and the control module controls, based on the location information, the self-moving gardening robot to move in the preset path mode. The preset path mode may be an algorithm. The self-moving gardening robot includes an ambient detection module, configured to detect an environment of a working area, and a control module, configured to generate a preset moving path or a preset target location based on the preset path mode and based on at least the ambient information and/or the location information, and to control the self-moving gardening robot to move along the preset moving path or to move toward the preset target location. The ambient detection module includes a camera, a collision detection sensor, or the like. Specifically, the control module generates a specific moving path or target location based on the preset path mode and according to an actual scenario in the working area and the location information of the self-moving gardening robot. For example, the control module generates a moving path bypassing an obstacle based on the obstacle in the working area, generates a spraying location or a fallen leaves storage location along a boundary based on the boundary of the current working area, and may also generate a target location by recording a location of the docking station. Certainly, the location of the docking station may alternatively be obtained based on an input or teaching of a user.
In this embodiment, the path planning unit stores at least two preset path modes, and the control module controls the self-moving gardening robot to respectively move in the corresponding preset path modes when performing at least two lawn care works.
When implementing a fallen leaves sweeping function, there are two modes for the self-moving gardening robot 100 to enter a fallen leaves area: (1) a user set mode; and (2) a self-learning mode. In the user set mode, the self-moving gardening robot 100 receives a user instruction through the wireless communication module 90. A user equipment 200 displays a working map interface of the self-moving gardening robot 100. The user designates, through a button or screen of the user equipment 200, the fallen leaves area, a travel path of the self-moving gardening robot 100 in the fallen leaves area, and a collection line location or a collection point location to which fallen leaves are collected by the self-moving gardening robot 100. After finishing the foregoing settings, the user sends a relevant instruction to the self-moving gardening robot 100 through the user equipment 200. In the self-learning mode, the self-moving gardening robot 100 determines the location of the fallen leaves area and the fallen leaves collection line location or the fallen leaves collection point location in the process of forming a working map through self-learning. A preset algorithm for the travel path in the fallen leaves area is provided in the control module 30 of the self-moving gardening robot 100. When the self-moving gardening robot 100 is in the fallen leaves area, the self-moving gardening robot travels and collects fallen leans along a path of the preset algorithm. In one of embodiments, in the fallen leaves area, the self-moving gardening robot 100 travels in a reciprocating manner along a preset path.
There may be one multi-functional accessory interface 12, configured to match mating parts corresponding to different functional accessories. There may alternatively be a plurality of multi-functional accessory interfaces 12, configured to respectively match mating parts corresponding to different functional accessories. In the foregoing embodiment, the mating parts of different accessories are all configured to match the multi-functional accessory interface 12 of the self-moving gardening robot 100, and therefore only one numeral 542 is used in the text to represent the mating parts of different accessories; this does not constitute a limitation that the mating parts of different accessories need to be of the same structure.
In one of embodiments, when the self-moving gardening robot 100 implements different functions, the control module 30 may control a travel speed of the moving module 20 to be different. When the self-moving gardening robot 100 performs different material functions, the control module 30 controls the travel speed of the moving module 20 according to an amount of a material needed per one square meter, a machine body area of the self-moving gardening robot 100, or/and a rotation speed of the cutting module.

The grass condition identification sensor 40 is a capacitive sensor. The capacitive sensor includes a detection electrode and the detection electrode is configured to sense a grass condition. The sensor further includes a reference electrode corresponding to the detection electrode. The detection electrode approaches the lawn. When the grass condition varies, a capacitance of the capacitive sensor changes. Specifically, the probe 41 serves as the detection electrode of the capacitive sensor, and the reference electrode serves as a circuit ground of the signal processing circuit or the ground. When the grass condition under the probe 41 varies, a capacitance value of the capacitive sensor varies, and a reference value of an output signal of the signal processing circuit also varies.

In one of embodiments, a match table between frequency ranges of the output signal and corresponding grass conditions is set in the control module 30. In this embodiment, a specific form of the grass condition match table is shown in table 1. Certainly, relevant parameters in the match table may change adaptively when a different signal processing circuit is used.
In one of embodiments, the self-moving gardening robot 100 includes a plurality of grass condition identification sensors 40, and heights of probes 41 of the plurality of grass condition identification sensors 40 are different one another. When height differences between the probe 41 and the grasses are different, output signals of signal processing circuits of the capacitive sensors are also different. The control module 30 determines a current height of grasses by identifying the output signals of the signal output circuits of the plurality of capacitive sensors.
It should be noted that in other embodiments, the output signal of the signal processing circuit is not limited herein. When the probe 41 senses a grass condition, the output signal of the signal processing circuit may alternatively be another signal, for example, a level signal, as long as the signal can represent whether the probe 41 has sensed the grass condition.
In another embodiment, the grass condition identification sensor 40 is an image sensor, specifically, a video camera, a photographic camera, or the like. The image sensor photographs an image of a lawn in a travel area of the self-moving gardening robot 100. The control module 30 analyzes the image and obtains a grass condition in the image area through a corresponding image processing algorithm. Specifically, for example, by counting and analyzing color information and texture information in the image, a water content of grasses (green grasses or withered grasses) and a density condition of grasses (a sparse grass condition or a dense grass condition) are determined, so as to determine a health condition of the grasses.
In another embodiment, the self-moving gardening robot 100 is further provided with an ambient sensor configured to sense a surrounding environment. There may be a plurality of or multiple types of ambient sensors, specifically, for example, a moisture sensor, a temperature sensor, a wind speed sensor, or a drench sensor. The self-moving gardening robot 100 senses ambient information through the ambient sensor and transmits the specific ambient information (for example, moisture information, temperature information, wind strength information, or rain condition information) to the user equipment 200 through the wireless communication module 90. The specific transmission method may include: the wireless communication module 90 directly transmits the ambient information to the user equipment 200, or the wireless communication module 90 first transmits the ambient information to the service end 300 and then the service end 300 transmits the ambient information to the user equipment 200. In this embodiment, the self-moving gardening robot 100 is similar to a mobile weather station, to remotely inform the self-moving gardening robot 100 of weather information of the environment of the self-moving gardening robot 100, thereby implementing one machine with multiple functions. Through the user equipment 200, a user may monitor information about the environment of the self-moving gardening robot 100 and learn about information such as moisture, temperature, wind strength, or whether there is rain in the environment of the self-moving gardening robot. In one of embodiments, the user may change a work plan of the self-moving gardening robot 100 based on current ambient information (for example, moisture information, temperature information, wind strength information, or rain condition information).

In another embodiment, the material replenishing device 500 may fixedly set a duration for which the automatic valve 501 is open. The duration for which the automatic valve 501 is open is determined based on a given volume of the material cavity 52 and a preset flow of the material pipe 503.
The automatic valve 501 may be specifically a normally closed solenoid valve. Before the self-moving gardening robot 100 is not successfully docked with the docking station 400, the solenoid valve is kept closed and the material cannot flow out. When the self-moving gardening robot 100 is successfully docked with the docking station 400, the docking station 400 provides electricity to the solenoid valve and the material flows out.
In this embodiment, the material replenishing device 500 is disposed in the docking station 400, whether the self-moving gardening robot 100 is moved to the preset location can be determined by using charging docking modules of the self-moving gardening robot 100 and the docking station 400. When the charging docking modules are successfully docked, it is considered that the self-moving gardening robot 100 has moved to the preset location. The control module in the docking station 400 controls the automatic valve 501 to be open. In one of embodiments, a tail 505 or an accessory of the material pipe 503 is provided with a circle of magnets, and a hall sensor 527 is disposed near an opening of the material cavity 52. The automatic valve 501 of the material replenishing device 500 is opened only when the hall sensor 527 senses a magnetic signal.
The docking determining method for the charging docking modules may be specifically a wired contact method through a current, a voltage, a communications protocol, or the like, or wireless non-contact method through infrared, ultrasound, Hall induction, uwb, or the like.

In an embodiment, the water supply is connected to a household water faucet and the material replenishing device 500 through a water pipe. A power supply of the docking station 400 is connected to a household power supply and the docking station 400 through a cable. To control costs and maintain water pressure of the water supply, the location selected for the docking station 400 is close to the household water faucet as far as possible, to reduce a length of the water pipe.
In one of embodiments, a water passage and an electricity passage of the docking station 400 are separated from each other and a water-proof layer and an insulation layer are provided between the water passage and the electricity passage.
In one of embodiments, to prevent electric short circuit of the self-moving gardening robot caused by water overflowing the material cavity 54 in the process of adding water to the self-moving gardening robot 100, for example, short circuit of an electric button on the housing due to water inflow, short circuit of a control board or an electronic circuit around the material cavity 54 due to water inflow, the material cavity 52 of the self-moving gardening robot 100 is provided with a water overflowing prevention structure.
In one of embodiments, the docking station 400 is also further provided with a nutrient solution box and a flow valve for controlling a flow of the nutrient solution. When water is added to the self-moving gardening robot 100, the flow valve is opened to enable the nutrient solution to mix with water and the flow to the material cavity 52.
There may alternatively be a plurality of material replenishing devices 500, respectively storing different materials. The self-moving gardening robot 100 automatically selects a corresponding material replenishing device 500 when needing a specific type of material. Certainly, the material replenishing device 500 may alternatively not use the same docking station 400 with the charging device. In one of embodiments, the charging device of the self-moving gardening robot 100 may use a wireless charging method. In one of embodiments, an accessory switching device may further be provided at the docking station 400. Accessories for implementing different functions are provided at the accessory switching device. When the self-moving gardening robot needs to switch a functional accessory, the self-moving gardening robot travels to a predetermined location of the accessory switching device and the accessory switching device automatically replaces the accessory carried by the self-moving gardening robot or automatically connects an accessory 54 of a corresponding function to the accessory interface 12 of the self-moving gardening robot.
In one of embodiments, the docking station 400 has a plurality of docking directions, and the self-moving gardening robot 100 may enter the docking station in different directions each time the self-moving gardening robot 100 returns.
In one of embodiments, the location of the docking station 400 is selected to be arranged on a hard ground other than a soft lawn.
In another embodiment, the moving module 20 uses an inflatable wheel, to prevent the self-moving gardening robot 100 from damaging a lawn, and an area of a cross section of the inflatable wheel satisfies a relationship of not crushing grasses. The area of the cross section of the inflatable wheel is associated with a weight of the self-moving gardening robot 100 and is also associated with an anti-crush coefficient of the working surface and the grasses.
The following content specifically introduces a working process for the self-moving gardening robot to implement multi-functional lawn maintenance.
The self-moving gardening robot 100 is provided with a function selection module. The function selection module performs a functional task prescribed by an instruction according to the received instruction. In an embodiment, the housing 10 of the self-moving gardening robot 100 is provided with a functional button (or another user input module) corresponding to different functions and a user triggers a function selection module through the functional button. In another embodiment, the self-moving gardening robot 100 is provided with a wireless communication module 90 and a user inputs or selects a corresponding functional option through a corresponding app client on the user equipment 200. The wireless communication module 90 receives the corresponding functional instruction and transmits the instruction to the function selection module. Certainly, the self-moving gardening robot 100 may alternatively be provided with both a functional button and a wireless communication module.
In one of embodiments, the self-moving gardening robot 100 is further provided with a full-automatic maintenance module automatically performing multi-functional tasks in order. A user sends an instruction through a housing button or a remote client to enable the full-automatic maintenance module, so that the self-moving gardening robot 100 enters a full-automatic lawn maintenance mode. In a specific embodiment, in the full-automatic lawn maintenance mode, the self-moving gardening robot 100 first starts a soil loosening function and then performs a sowing function, followed by a water spraying function, a fertilizing function, a grass cutting function, and a withered grass removing function. Specific parameters such as a sequence of the respective functions, time intervals between the respective functions, and a repeated time of the respective functions are not limited herein. The dealer or manufacturer of the self-moving gardening robot 100 may fix the parameters values in the full-automatic maintenance module based on big data statistics of lawn maintenance. In one of embodiments, a variable interface for the foregoing parameters is reserved in the full-automatic maintenance module and a user may adjust the foregoing parameters according to needs. In the full-automatic lawn maintenance mode, participation of a user and functional switch are no longer needed in daily maintenance actions by the self-moving gardening robot 100, such as sowing, fertilizing, water spraying, pesticides spraying, and withered grass removing for a lawn, and the self-moving gardening robot 100 can adaptively finish the actions.
Certainly, a user may alternatively input specific working time plan information through a housing button or a remote client.
In one of embodiments, the functional tasks can be grouped into high-frequency functional tasks and low-frequency functional tasks based on different frequencies at which the functional tasks are performed. For example, the grass cutting function, the water spraying function, and the fallen leaves collecting function may be set to be high-frequency functional tasks; and the soil loosening function, the sowing function, and the withered grass removing task may be set to be low-frequency functional tasks. When the self-moving gardening robot 100 performs a high-frequency functional task, the grass condition identification sensor 40 counts and/or updates grass condition information of the whole working area. The control module 30 determines, according to the grass condition information, a part of the working area on which a low-frequency functional task needs to be performed. The control module 30 controls the self-moving gardening robot 100 to automatically enter the part of the working area to perform the corresponding low-frequency functional task, or to prompt the user of the specific low-frequency functional task that needs to be performed on the part of the working area, so that the user performs functional task switch.
The self-moving gardening robot 100 may finish all task of courtyard maintenance by switching different functional tasks. In a specific implementation, for example, the self-moving gardening robot 100 automatically performs a high-frequency functional task, such as a grass cutting task or a water spraying task, according to a schedule. In this embodiment, the self-moving gardening robot 100 performing a grass cutting task is used as an example. In the process in which the self-moving gardening robot 100 performs the grass cutting task, the grass condition identification sensor 40 identifies a health condition of the lawn in the working area and transmits the health condition to the user equipment 200 through the wireless communication module 90. After the self-moving gardening robot 100 traverses the whole working area, the grass condition identification sensor 40 identifies the grass condition of the whole working area. The user equipment 200 or the service end 300 sends function switch prompt information to the user based on a preset algorithm and according to the grass condition or the self-moving gardening robot 100 automatically switches and performs another functional task. Specifically, when the grass condition indicates that a withered grass area is large, the user equipment 200 prompts relevant functional tasks such as grasses removing, soil loosening, and sowing. Under the prompt of the user, the functional tasks of the self-moving gardening robot 100 are sequentially switched. Specifically, when the grass condition indicates that the moisture of the lawn is excessively low, the self-moving gardening robot 100 automatically starts the water spraying task after finishing the grass cutting task. Certainly, only one specific scenario is described for automatic switch and manual switch of the functional tasks, and a change in the scenarios does not constitute a limitation to the automatic switch and manual switch.
In one of embodiments, the control module of the self-moving gardening robot 100 is provided with a schedule arrangement module. The schedule arrangement module distributes a time arrangement for performing different functions and/or a time arrangement for performing one same function for the self-moving gardening robot 100 according to date or season information. In a specific embodiment, the schedule arrangement module may store a time arrangement list according to annual grow rules of grasses in all regions around the world and used for performing different functions by the self-moving gardening robot 100. The rules can be obtained through meteorological statistics data.
In another embodiment, the schedule arrangement module may alternatively be operated by a user to set working frequencies at which the self-moving gardening robot 100 performs the different functions. For example, when performing the water spraying function, the self-moving gardening robot 100 is set to have a working frequency of 3 days each time and to work for a predetermined time each time; or, the self-moving gardening robot 100 is set to merely work on Tuesday and Saturday within a week and to work for a predetermined time each time. In one of embodiments, the self-moving gardening robot 100 may intelligently adjust the working frequency of water spraying according to a weather condition. When it is predicted to rain in the weather forecast, the water spraying frequency is reduced intelligently to avoid a raining day. In one of embodiments, the self-moving gardening robot 100 may intelligently compare, based on an irrigation amount each week recommended according to local climate and a grass condition, a water spraying frequency and a total water spraying amount each time set by a user, to automatically increase or decrease the water spraying frequency and the total water spraying amount each time.
The self-moving gardening robot 100 may be a single functional irrigating robot to perform a water spraying or flower watering function. In this embodiment, the self-moving gardening robot 100 does not need to use the same machine body with the foregoing functions such as grass cutting and fertilizing, and does not need to externally connect an accessory to implement functions such as soil loosening, withered grass removing, and fallen leaves sweeping. Correspondingly, a hardware part of the self-moving gardening robot 100 can be simplified or slightly changed. For example, the cutting module 56 no longer needs to be disposed in the working module 50 and the multi-functional accessory interface 12 no longer needs to be disposed in the housing 10. The self-moving gardening robot 100 performing the water spraying function is used as an example in the following content to introduce the whole process for the self-moving gardening robot 100 to finish the water spraying task in the working area.
After the self-moving gardening robot 100 receives a water spraying task instruction, the capacity detection device 524 detects a residual water amount in the material cavity 52. If the residual water amount is insufficient, the control module 30 controls the self-moving gardening robot 100 to return to the material replenishing device 500, for water supply. If the residual water amount is sufficient, the control module 30 controls the self-moving gardening robot 100 to travel in the working area from the start point and start to perform the water spraying work.
In the water spraying process, the self-moving gardening robot 100 controls the material opening 523 to be open and water falls from the material opening 523. When the self-moving gardening robot 100 uses the same machine body with the grass cutting function, the control module 30 starts the rotation speed control unit, to control the cutting module 56 to rotate at a low speed. The cutting module 56 rotates to drive the fallen water to evenly spread toward the lawn.
Certainly, the water spraying process may also be completed by using a drip irrigation device or a spraying device. In the automatic moving process of the self-moving gardening robot 100, the drip irrigation device is opened and water drops, from the material cavity through the drip irrigation device, on an area of a path through which the self-moving gardening robot 100 moves. When a spraying device is used in the water spraying process, the water spraying process is similar to a drip irrigation and water spraying process.
The self-moving gardening robot 100 has a precise water spraying working mode and a common water spraying working mode. In the common water spraying working mode, in the travel process of the self-moving gardening robot 100, the material opening is kept to be open, to spray water to the working area through which the self-moving gardening robot 100 travels. In the mode, the self-moving gardening robot 100 does not need to depend on the grass condition detected by the grass condition identification sensor 40, to perform water spraying control.
In the precise water spraying working mode, the grass condition identification sensor 40 detects a grass condition of an area where the self-moving gardening robot 100 is located and transmits the grass condition signal to the control module 30. The control module 30 controls opening and closing of the hatch of the material opening 523 according to the grass condition signal. When the grass condition identification sensor 40 identifies that the grass condition in the area where the self-moving gardening robot 100 is located is good, the control module 30 determines that water spraying is not needed in the area and therefore controls the material opening 523 to be closed. When the grass condition identification sensor 40 identifies that the grass condition in the area where the self-moving gardening robot 100 is located is poor, the control module 30 determines that water spraying is needed in the area and therefore controls the hatch of the material opening 523 to be open. In the precise water spraying working mode, the self-moving gardening robot 100 merely performs water spraying on a lawn area needing water spraying, thereby achieving the objective of saving water and avoiding impact on the grass condition and growth of the whole lawn due to abuse of water spraying.
In one of embodiments, the precise water spraying location may be transmitted to an application corresponding to the user equipment 200 trough the wireless communication module 90. A user learns about the locations on which precise water spraying has been performed and the total number of corresponding location points through an application interface. In another implementation process, the user may also designate, through the application interface, locations needing precise water spraying, and the application transmits the instruction to the self-moving gardening robot 100 in a wireless manner. The self-moving gardening robot 100 enters the designated location point to perform water spraying and transmits completion information to the application after precise water spraying is done at the preset location. Through the application interface, the user learns about a relevant condition of completion of precise water spraying at a location by the self-moving gardening robot 100.
In a implementation process, the self-moving gardening robot 100 is provided with a positioning module 70, and the travel mode of the self-moving gardening robot 100 in the working area is travelling along a planned path. The positioning module 70 positions a location of the self-moving gardening robot 100 and transmits the location information to the control module 30. The control module 30 compares the location information and planned path data, to control a travel direction of the self-moving gardening robot 100. In one of embodiments, the self-moving gardening robot 100 automatically traverses the whole working area with the assist of the positioning module 70. The control module 30 controls the self-moving gardening robot 100 not to travel to a lawn area on which water has been sprayed, thereby preventing the self-moving gardening robot 100 from damaging the lawn or leaving a wet tracing rut on the lawn, and meanwhile preventing the self-moving gardening robot 100 from performing repeated water spraying on the same area. After the self-moving gardening robot 100 traverses the whole working area, the self-moving gardening robot 100 stops the water spraying function.
In this embodiment, the self-moving gardening robot 100 may perform self-learning by using the positioning module 70, to determine a working map of the working area. Specifically, the user controls the self-moving gardening robot 100 or takes out the positioning module 70, to walk around the working area along the borders, so that the self-moving gardening robot 100 records the travel track and defines the track as a boundary of the working area; or to walk around an obstacle point in the working area, so that the self-moving gardening robot 100 records the track and defines the track as an obstacle area; or to walk around a flower bed or a flower garden, so that the self-moving gardening robot 100 records the track and defines the track as a flower garden area; or to walk around a predetermined radius of a tree, so that the self-moving gardening robot 100 records the track and defines the track as a fallen leaves area; or to walk around an area such as a pool or a steep slope that is not suitable for the self-moving gardening robot 100 to enter, so that the self-moving gardening robot 100 records the track and defines the track as a dangerous area. The control module 30 of the self-moving gardening robot 100 determines different water spraying policies based on a preset algorithm and according to a formed map and a sign in the map.
In this embodiment, the storage unit of the self-moving gardening robot 100 stores a map of the working area 3. After the self-moving gardening robot 100 is positioned, the self-moving gardening robot 100 can identify its location on the map. In one of embodiments, the map information of the working area 3 stored in the storage unit may update according to a state of the working area traversed by the self-moving machine 100 each time.
In one of embodiments, the map of the self-moving gardening robot 100 has an automatic update function. When the self-moving gardening robot 100 encounters an obstacle in the working area, the self-moving gardening robot circles around the obstacle to generate an island and updates map information of the island to the map in the storage unit.
In one of embodiments, when a grassland condition in the working area changes, the self-moving gardening robot 100 receives the change and marks the changed area on the map, to further change the water spraying policy for the area. Specifically, sowing is again performed on a subarea in the working area. During sowing, a sowing machine transmits map information of the subarea to the self-moving gardening robot 100. The self-moving gardening robot 100 marks the newly sowed area in the existing map, and the control module 30 automatically changes the water spraying policy of the newly sowed area according to an amount of water needed for a growth cycle of the type of grasses, specifically, for example, reducing the water spraying frequency in the area or reducing the water spraying amount of each water spraying. Certainly, if the sowing machine does not have a map coordinate marking function, the map information of the newly sowed area may also be manually updated by a user and transmitted to the self-moving gardening robot 100.
In one of embodiments, after the working area map of the self-moving gardening robot 100 is formed, the self-moving gardening robot 100 may automatically divide the working area, to implement a partition water spraying policy.
In one of embodiments, the self-moving gardening robot 100 may further divide each working subarea when performing water spraying on the working subarea.
Water spraying in the small subarea by the self-moving gardening robot 100 may specifically use a drip irrigation manner or a sprinkling irrigation manner. In an embodiment, as shown in
In one of embodiments, partition of the working subarea by the self-moving gardening robot 100 is dynamically changing. Specifically, the small subareas obtained by dividing the working subarea A by the self-moving gardening robot 100 the first time are shown in
When performing irrigation on each working subarea, the self-moving gardening robot 100 performs irrigation on each small subarea in a manner of from far to near by using the docking station 400 as a base point. As shown in
In one of embodiments, the irrigation policies of the self-moving gardening robot 100 for a working area having a slope and a working area not having a slope are different. Specifically, the irrigation amounts needed by the grasses on a slope facing the sun and on a slope facing north are different from that of grasses on flat surfaces. Therefore, the irrigation frequency and irrigation amount on the grasses on the slope facing the sun by the self-moving gardening robot 100 may adaptively be increased and the irrigation frequency and irrigation amount on the grasses on the slope facing north may adaptively be reduced. In one of embodiments, when a slope angle of a slope land is excessively large and the slope land is not suitable of the self-moving gardening robot 100 to travel, the self-moving gardening robot 100 may select to perform irrigation in a sprinkling irrigation below or above the slope land. In one of embodiments, when constructing the working area map of the self-moving gardening robot 100, the user may mark a slope facing the sun and a slope facing north, and the self-moving gardening robot 100 may automatically determine the slope facing the sun and the slope facing north according to the mark when travelling to a specific area.
In a implementation process, the self-moving gardening robot 100 is provided with a positioning module 70. The storage unit of the control module 30 records location information of the self-moving gardening robot 100 when implementing water spraying. Therefore, the self-moving gardening robot 100 may implement not repeatedly spraying water at the same water spraying location point. The control module 30 first determines whether a location of the self-moving gardening robot 100 is a water spraying position recorded in the storage unit; if yes, the control module 30 controls the working module for spraying water not to work; otherwise, the control module 30 controls the water spraying module to work.
In a implementation process, the self-moving gardening robot 100 is provided with a positioning module 70. When the self-moving gardening robot 100 needs to interrupt water spraying to replenish water supply, the storage unit of the control module 30 records the interrupted location information and the traveling direction at this time and controls the self-moving gardening robot 100 to move to the docking station according to the preset moving path or the preset target location, to replenish water supply. After the self-moving gardening robot 100 completes replenishing water supply, the control module 30 controls the self-moving gardening robot 100 to travel to the interrupted position and to travel in the original direction, to perform the water spraying task.
In a implementation process, the self-moving gardening robot 100 is provided with a positioning module 70, and the storage unit of the control module 30 records location information of the self-moving gardening robot 100 during the travel process and grass condition information identified by the grass condition identification sensor 40 for the location information. After the self-moving gardening robot 100 travels to cover the whole lawn, the storage unit records grass condition information of the whole lawn.
In a implementation process, the self-moving gardening robot 100 is provided with a wireless communication module 90, and a user learns about a state of the self-moving gardening robot 100 and controls the self-moving gardening robot 100 through the user equipment 200. Specifically, the capacity detection device 524 detects a material residual amount in the material cavity 52 and transmits the material residual amount to the service end 300. The service end 300 receives material residual amount data and determines whether to add a material, so as to generate a prompt instruction. The service end 300 transmits the material residual amount data and the prompt instruction to a corresponding app program or application on the user equipment 200. The corresponding app program or application or app or application interface of the user equipment 200 displays the material residual amount data and a material addition prompt state.
The corresponding app program of the user equipment 200 is provided with an instruction input port, for a user to remotely control the self-moving gardening robot 100. The specific control instructions include: various control instructions such as setting a working schedule of the self-moving gardening robot 100, performing functional selection or switch, setting relevant parameters of the self-moving gardening robot 100, enabling the self-moving gardening robot 100 to start work, and commanding the self-moving gardening robot 100 to return to the docking station 400.
In one of embodiments, the self-moving gardening robot 100 is further provided with a grass condition identification sensor 40. The app or application interface of the user equipment 200 may display grass condition of a current location of the self-moving gardening robot 100.
In one of embodiments, the self-moving gardening robot 100 is also provided with a positioning module 70, and the app interface of the user equipment may display the grass condition of the whole lawn. The wireless communication module 90 transmits data of each location of the lawn and grass condition at the location to the service end 300, and the service end 300 counts lawn information of the whole lawn, to form a grass condition thumbnail image corresponding to the lawn map or a grass condition data ratio of the whole lawn. In one of embodiments, the app or application interface of the user equipment displays the lawn map, and the grass conditions in all the areas of the lawn map are marks in colors. An area with a good grass condition is shown in green, an area with an intermediate grass condition is shown in yellow, and an area with a poor grass condition is shown in red. Through the interface, a user may clearly learn about the grass conditions in all areas of the whole lawn. In one of embodiments, the app interface of the user equipment may further display an operation prompt according to the statistic grass condition information. Specifically, when a withered grass ratio in the statistic grass conditions reaches 10% of the area of the lawn, the app interface of the user equipment displays and prompts a user the specific functions to be implemented: for example, implementing a withered grass removing function, implementing a re-sowing function, implementing a water spraying function, and implementing a fertilizing function.
In an embodiment, by disposing a wireless transmission relay or using a long-distance coverage wireless communications device, all points in the working area 3 are covered with a wireless network. The self-moving gardening robot 100 can be wirelessly connected to the service end 300 at any point in the working area 3. The self-moving gardening robot 100 interacts with the service end in real time in the working area 3, to transmit data and receive instructions. In other embodiments, if the self-moving gardening robot 100 works in a working area of an ultra large range, a part of the working area is covered by the wireless network and the other part of the working area is not covered by the wireless network. The wireless communication module 90 can be connected to the service end 300 only when the self-moving gardening robot 100 is in the part of area covered by the wireless network. In this embodiment, the self-moving gardening robot 100 stores work data or grass condition data through the storage unit of the control module 30. When the self-moving gardening robot 100 enters the part of area covered by the wireless network, the control module 30 transmits data that has been stored in the storage unit to the service end 300 through the wireless transmission module 90.
In one of embodiments, the self-moving gardening robot 100 obtains local weather forecast information through the wireless communication module 90. The control module 30 controls the self-moving gardening robot 100 to perform or not to perform a water spraying function according to the obtained weather forecast information. A specific example is described below. According to a schedule or a user instruction, the self-moving gardening robot 100 needs to perform a water spraying task today. Before performing the water spraying task, the self-moving gardening robot 100 first obtains weather condition information of next three days through the wireless communication module 90. If it is predicted to have rain in the next three days, the wireless communication module 90 transmits the information to the control module 30. The control module 30 controls the self-moving gardening robot 100 not to perform the water spraying function temporarily. In other embodiments, obtaining of the weather conditions and control of instruction generation may alternatively be completed by the service end 300.
When there are still flower plants in the working area 3 in addition to the lawn, the process for the self-moving gardening robot 100 to perform flower watering for the flowers is shown in
When the self-moving gardening robot 100 separately performs other functions such as grass cutting, fertilizing, sowing, pesticides spraying, soil loosening, withered grass removing, and fallen leaves collecting or when the self-moving gardening robot 100 is integrated with multiple functions and respectively perform the individual function, the part of the working process similar to that in the working process of performing the water spraying function is not described in detail again herein.
Certainly, the material of the self-moving gardening robot 100 may alternatively be directly added manually by a user. When the material in the material cavity 52 is less than a preset threshold, the self-moving gardening robot 100 prompts a user to add the material. For example, the self-moving gardening robot 100 transmits prompt information to the corresponding application of the user equipment 200 through the wireless transmission module 90, or self-moving gardening robot 100 sends a prompt signal such as a sound or light.
Certainly, when the self-moving gardening robot 100 performs some functions, the travel mode of the self-moving gardening robot 100 in the working area is also random travel. The self-moving gardening robot 100 travels randomly in the working area multiple times, to cover the whole working area.
The following describes details of the complete working process for the self-moving gardening robot to implement different functions.
Step S11: Monitor a health condition of a lawn and according to a grass condition, prompt a user of whether a sowing operation needs to be performed. In the step, the health condition of the lawn may be collected and obtained by a grass condition identification sensor 40 in a process in which the self-moving gardening robot 100 traverses a working area when the self-moving gardening robot 100 performs another functional task (for example, a grass cutting task). When the grass condition shows that there is a withered grass area or an accumulated area of withered grass areas is large, the self-moving gardening robot 100 sends a sowing task prompt to a user equipment 200 through a wireless communication module 90.
Step S12: After the user receives the sowing task prompt, the user injects corresponding seeds to a material cavity 52 of the self-moving gardening robot 100, and switches a working mode of the self-moving gardening robot 100 to a sowing mode.
Step S13: In the sowing working mode, the self-moving gardening robot 100 finds the withered grass area by using the grass condition identification sensor 40, finds the withered grass area, according to a withered grass location point stored in the process of monitoring the health condition of the lawn, or finds the withered grass area by receiving a withered grass location point selected by the user. The self-moving gardening robot 100 enters the withered grass area, to perform sowing. In the sowing process, the self-moving gardening robot 100 simultaneously monitors a residual amount of seeds in the material cavity 52. The specific monitoring method may be implemented by using the foregoing capacity detection device 524. When the residual amount of seeds is less than a preset capacity, the self-moving gardening robot 100 sends, to the user equipment 200 through the wireless communication module 90, prompt information of adding seeds.
Step S14: When the user receives the prompt information of adding seeds, the user again injects the corresponding seeds to the material cavity 52 of the self-moving gardening robot 100.
Step S15: After the self-moving gardening robot 100 completes the sowing task for all withered grass areas, the user or the self-moving gardening robot 100 switches so that the self-moving gardening robot 100 enters another working mode, is turned off, or returns to a docking station 400 for docking. In the step, the self-moving gardening robot 100 may determine whether the sowing task for all the withered grass areas is completed by traversing the lawn, or determine whether the sowing task is performed on the stored withered grass location point or the withered grass location point pointed by the user.
If the area of the withered grass area is large, step S13 and step S14 need to be repeated multiple times in the process in which the self-moving gardening robot 100 completes the sowing task for all the withered grass areas.
In the specific implementation process, the seeds are added by the user manually. As described above, the self-moving gardening robot 100 may automatically return to the docking station 400 for automatically adding seeds. The specific adding process is not described in detail herein.
In the process in which the self-moving gardening robot 100 performs the sowing task, if electric energy insufficiency appears to the self-moving gardening robot 100, the self-moving gardening robot 100 automatically returns to the docking station 400 for replenishing electric energy.
The scenario and workflow for the self-moving gardening robot 100 to perform a fertilizing function are similar to those for the self-moving gardening robot 100 to perform the sowing function, and therefore the workflow for the self-moving gardening robot 100 to perform the fertilizing function may also refer to

In the step, there are specifically two methods for arrangement of the water spraying working schedule. Method 1: A user manually sets a water spraying working schedule of the self-moving gardening robot 100. The specific setting method and schedule may refer to the working process for the self-moving gardening robot to implement multi-functional lawn maintenance described in the foregoing text. Method 2: The self-moving gardening robot 100 obtains weather information through a wireless communication module 90 and according to the weather information, lawn moisture monitoring information, and a working schedule of a task such as grass cutting, automatically sets a water spraying working schedule or automatically modifies a water spraying working schedule set by a user.

The specific monitoring method may be implemented by using the foregoing capacity detection device 524.
Step S23: When the residual amount of water is less than a preset capacity, the self-moving gardening robot 100 automatically returns to a docking station 400 for replenishing water.
Step S24: After water replenishing is completed, the self-moving gardening robot 100 returns to a work interrupted point and continuously performs the water spraying task. The specific workflow of step S23 and step S24 may refer to relevant content of the working process for the self-moving gardening robot to implement multi-functional lawn maintenance described in the foregoing text.
Step S25: After the self-moving gardening robot 100 completes the water spraying task, the user or the self-moving gardening robot 100 switches so that the self-moving gardening robot 100 enters another working mode, is turned off, or returns to a docking station 400 for docking. In the step, the self-moving gardening robot 100 determines whether the water spraying task is completed after traversing all lawn areas.
If the area needing water spraying is large, step S22 to step S24 need to be repeated multiple times in the process in which the self-moving gardening robot 100 completes the water spraying task. In one of embodiments, the self-moving gardening robot 100 selects a path on which water spraying is not performed to travel each time the self-moving gardening robot 100 goes back and forth between the interrupted point and the docking station.
In the process in which the self-moving gardening robot 100 performs the water spraying task, if electric energy insufficiency appears to the self-moving gardening robot 100, the self-moving gardening robot 100 automatically returns to the docking station 400 for replenishing electric energy.
Step S31: The self-moving gardening robot 100 obtains courtyard map information, location information of a flower garden, and flower garden shape information. In the step, the specific process for obtaining the map information and a location and shape information of the flower garden may refer to relevant content of the working process for the self-moving gardening robot to implement multi-functional lawn maintenance described in the foregoing text.
Step S32: The self-moving gardening robot 100 receives a flower watering working schedule and enables a flower watering working mode. In the step, there are specifically two methods for arrangement of the flower watering working schedule. Method 1: A user manually sets a flower watering working schedule of the self-moving gardening robot 100. The specific setting method and schedule may refer to relevant content of the working process for the self-moving gardening robot to implement multi-functional lawn maintenance described in the foregoing text. Method 2: The self-moving gardening robot 100 obtains weather information through a wireless communication module 90 and according to the weather information, lawn moisture monitoring information, and a working schedule of a task such as grass cutting, automatically sets a flower watering working schedule or automatically modifies a flower watering working schedule set by a user.
Step S33: The self-moving gardening robot 100 automatically waters flowers and monitors a residual amount of water in a material cavity 52. The flower watering mode may be implemented by using the spraying device 526 described in the foregoing text. The specific process of automatic flower watering may refer to relevant content of the working process for the self-moving gardening robot to implement multi-functional lawn maintenance described in the foregoing text. The specific monitoring method may be implemented by using the foregoing capacity detection device 524.
Step S34: When the residual amount of water is less than a preset capacity, the self-moving gardening robot 100 automatically returns to a docking station 400 for replenishing water.
Step S35: After water replenishing is completed, the self-moving gardening robot 100 returns to a flower garden point and continuously performs the flower watering task. The specific workflow of step S34 and step S35 may refer to relevant content of the working process for the self-moving gardening robot to implement multi-functional lawn maintenance described in the foregoing text.
Step S36: After the self-moving gardening robot 100 completes the flower watering task, the user or the self-moving gardening robot 100 switches so that the self-moving gardening robot 100 enters another working mode, is turned off, or returns to the docking station 400 for docking. In the step, the self-moving gardening robot 100 determines whether the flower watering task is completed after traversing all flower garden location points.
If the area of the flower garden needing to be watered is large, step S33 to step S35 need to be repeated multiple times in the process in which the self-moving gardening robot 100 completes the flower watering task.
In the process in which the self-moving gardening robot 100 performs the flower watering task, if electric energy insufficiency appears to the self-moving gardening robot 100, the self-moving gardening robot 100 automatically returns to the docking station 400 for replenishing electric energy.
Step S41: The user installs a fallen leaves raking accessory 54d to a multi-functional accessory interface 12 of the self-moving gardening robot 100.
Step S42: The self-moving gardening robot 100 obtains courtyard map information, location information of a fallen leaves area, and fallen leaves area shape information. In the step, the specific process for obtaining the map information and a location and shape information of the fallen leaves area may refer to relevant content of the working process for the self-moving gardening robot to implement multi-functional lawn maintenance described in the foregoing text.
Step S43: The self-moving gardening robot 100 enables a fallen leaves sweeping working mode. In the step, there are specifically two methods for enabling of the fallen leaves sweeping working mode. Method 1: The user has set the fallen leaves sweeping schedule, and the self-moving gardening robot 100 automatically enables the fallen leaves sweeping working mode at a predetermined time according to the schedule. Method 2: The user directly enables the fallen leaves sweeping working mode manually.
Step S44: The self-moving gardening robot 100 automatically performs a fallen leaves raking working task and monitors a working process. The specific process of automatically performing a fallen leaves raking working task may refer to relevant content of the working process for the self-moving gardening robot to implement multi-functional lawn maintenance described in the foregoing text.
Step S45: After the self-moving gardening robot 100 completes the fallen leaves raking task, the user or the self-moving gardening robot 100 switches so that the self-moving gardening robot 100 enters another working mode, is turned off, or returns to the docking station 400 for docking. In the step, the self-moving gardening robot 100 determines whether the fallen leaves sweeping task is completed after traversing all fallen leaves area location points.
In the process in which the self-moving gardening robot 100 performs the fallen leaves sweeping task, if electric energy insufficiency appears to the self-moving gardening robot 100, the self-moving gardening robot 100 automatically returns to the docking station 400 for replenishing electric energy.
By mating a withered grass removing or soil loosening accessory, the scenario and workflow for the self-moving gardening robot 100 to perform a withered grass removing or soil loosening function are enabled to be similar to those for the self-moving gardening robot 100 to perform the fallen leaves sweeping function, and therefore the workflow for the self-moving gardening robot 100 to perform the withered grass removing or soil loosening function may also refer to
In an embodiment, the self-moving gardening robot 100 further has a function of identifying normal grasses and weeds. As shown in
There is a plurality of methods for the self-moving gardening robot 100 to remove weeds. Method 1: Mechanically remove weeds. An accessory interface of the self-moving gardening robot 100 is connected to a weeding accessory and the weeding accessory is run on an identified weeds area, to pull out or cut the weeds. The specific mechanical structure of the weeding accessory may be similar to the soil loosening accessory or the withered grass removing accessory in the foregoing text, or is an individual grass pull mechanism or individual grass cutting mechanism. Method 1: Chemically remove weeds. The material cavity 52 of the self-moving gardening robot 100 stores a chemical agent for removing weeds. On an identified weeds area, a material outlet 523 is opened to drop/eject/spray the chemical agent to the weeds.
In this embodiment, there may be multiple types of image identification algorithms in the control module 30 for identifying weeds and normal grasses.
Step S51: An image sensor 60 obtains an image of a target area 70 and transmits the image to the control module 30.
Step S52: The control module 30 performs preprocessing on the image. The image preprocessing step includes operations such as enhancement and color model conversion on the image.
Step S53: The control module 30 performs texture extract on the preprocessed image.
Step S54: The control module 30 performs image cutting on the image on which texture extract has been performed.
Step S55: The control module 30 counts a profile size and shape of the cut image.
Step S56: The control module 30 compares the counted profile size and shape with a profile size and shape of normal grasses prestored in a memory, if a comparison result difference is within a preset range, determines that the grasses corresponding to the image are normal grasses, and otherwise, determines that the grasses are weeds.
In one of embodiments, before step S52, the control module 30 performs partition on the obtained image. Specifically, as shown in
Step S61: An image sensor 60 obtains an image of a target area 70 and transmits the image to the control module 30.
Step S62: The control module 30 performs preprocessing on the image. The image preprocessing step includes operations such as enhancement and color model conversion on the image.
Step S63: The control module 30 performs operator transformation on the preprocessed image. The specific operation of the operator transformation includes Haar operator transformation, Fourier transformation, or wavelet transformation of other forms.
Step S64: The control module 30 filters the transformed image. A filter operator is set according to an actual condition of normal grasses or weeds in the lawn.
Step S65: The control module 30 compares the filtered image and a preset image of normal grasses, if a comparison result difference is within a preset range, determines that the grasses corresponding to the image are normal grasses, and otherwise, determines that the grasses are weeds.
In one of embodiments, before step S62, the control module 30 performs partition on the obtained image. Specifically, as shown in
In another embodiment, the function of the self-moving gardening robot 100 for identifying normal grasses and weeds may alternatively be implemented by using a spectrum sensor. The housing 10 of the self-moving gardening robot 100 is provided with a spectrum sensor. The spectrum sensor obtains spectrum data in the target area 70. The control module 30 receives the spectrum data obtained by the spectrum sensor and compares the spectrum data and a spectrum range of normal grasses prestored in the memory, if the spectrum data is within the spectrum range of the normal grasses, determines that the grasses in the area corresponding to the spectrum data are normal grasses, and otherwise, determines that the grasses are weeds. Certainly, a spectrum range of weeds may alternatively be preset in the memory. If the spectrum data obtained by the spectrum sensor is within the spectrum range of weeds, it is determined that the grasses in the area corresponding to the spectrum data are weeds and the control module 30 controls the self-moving gardening robot to enter the corresponding area to perform a weeds removing action.
The present invention is not limited to the specific embodiment structure and all structures based on the concept of the present invention fall within the protection scope of the present invention.
