The present disclosure relates to the technical field of artificial intelligence, and in particular to a cleaning method, a window wiping robot, and a storage medium.
With the development of an artificial intelligence technology, cleaning robots, such as floor sweeping robots, window wiping robots, or cleaning machines, gradually enter people's daily life, which bring great convenience to people's life. In particular, the window wiping robots not only liberate people from heavy household chores, but also reduce the risk of aerial work. However, the cleaning efficiency of existing window wiping robots is low.
Aspects of the present disclosure provide a cleaning method, a window wiping robot, and a storage medium for improving the cleaning efficiency of the window wiping robot.
Embodiments of the present disclosure provide a cleaning method, including:
if a window wiping task needs to be performed, controlling a window wiping robot to spin to detect a boundary of a glass window to be cleaned; and
if a first boundary of the glass window to be cleaned is detected during spinning of the window wiping robot, controlling the window wiping robot to perform the window wiping task along the first boundary.
Embodiments of the present disclosure also provide a window wiping robot, including: a machine body provided with one or more processors and one or more memories for storing computer instructions.
The one or more processors are configured to execute the computer instructions for:
if a window wiping task needs to be performed, controlling a window wiping robot to spin to detect a boundary of a glass window to be cleaned; and
if a first boundary of the glass window to be cleaned is detected during spinning of the window wiping robot, controlling the window wiping robot to perform the window wiping task along the first boundary.
Embodiments of the present disclosure also provide a computer-readable storage medium, storing computer instructions. The computer instructions, when executed by one or more processors, cause the one or more processors to perform actions including:
if a window wiping task needs to be performed, controlling a window wiping robot to spin to detect a boundary of a glass window to be cleaned; and
if a first boundary of the glass window to be cleaned is detected during spinning of the window wiping robot, controlling the window wiping robot to perform the window wiping task along the first boundary.
According to the embodiments of the present disclosure, when a window wiping task needs to be performed, the window wiping robot firstly spins to detect a boundary of a glass window to be cleaned. If the boundary of the glass window to be cleaned is detected during spinning, the window wiping robot performs the window wiping task directly along the boundary. The cleaning mode can save the boundary detection time and help to improve the cleaning efficiency when starting to perform the window wiping task without detecting the boundary up, down, left, and right.

In the drawings:
For making the purposes, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in combination with the drawings in the embodiments of the present disclosure. It is apparent that the described embodiments are not all embodiments but part of embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art on the basis of the embodiments in the present disclosure without creative work shall fall within the scope of protection of the present disclosure.
An existing window wiping robot starts to perform a window wiping task by first detecting boundaries of a glass window to be cleaned and then selecting a cleaning mode. However, the window wiping robot takes a lot of time to detect the boundaries of the glass window to be cleaned, and the cleaning efficiency is low.
With regard to the technical problem of low cleaning efficiency of the existing window wiping robot, the embodiments of the present disclosure provide a solution with a basic idea as follows. When a window wiping task needs to be performed, the window wiping robot firstly spins to detect at least one boundary of a glass window to be cleaned. If at least one boundary of the glass window to be cleaned is detected during spinning, the window wiping robot performs the window wiping task directly along the detected boundary. The cleaning mode may save the boundary detection time and help to improve the cleaning efficiency when starting to perform the window wiping task without detecting all the boundaries, the up, down, left, and right.
The technical solutions provided by the embodiments of the present disclosure are described in detail below with reference to the drawings.
It should be noted that like reference numerals refer to like objects in the following drawings and embodiments, and thus, once an object is defined in one drawing or embodiment, further discussion thereof is not required in subsequent drawings and embodiments.
The machine body 101 is an actuator of the window wiping robot 100 that may perform operations specified by the processor 102 in certain environments. The machine body 101 reflects an appearance of the window wiping robot 100 to some extent. In the present embodiment, the appearance of the window wiping robot 100 is not limited. For example, the window wiping robot 100 may be a circular robot as shown in
It should be noted that some basic components of the window wiping robot 100, such as a driving component, an odometer, a power component, and an audio component, are also provided on the machine body 101. Optionally, the driving component may include a driving wheel, a driving motor, a universal wheel, a triangular track wheel, or a Mecanum wheel, etc. The basic components and the composition of the basic components contained in different window wiping robots 100 are different, and only some examples are listed in the embodiments of the present disclosure.
The power component is configured to supply power to various components of the window wiping robot. The power component may include a power management system, one or more power supplies, and other components associated with generation, management, and distribution of power for a device in which the power component is located.
The audio component may be configured to output and/or input an audio signal. For example, the audio component includes a microphone (MIC) configured to receive an external audio signal when a device in which the audio component is located is in an operational mode, such as a call mode, a recording mode, and a speech recognition mode. The received audio signal may be further stored in a memory or transmitted via a communication component. In some embodiments, the audio component further includes a loudspeaker for outputting the audio signal. For example, a window wiping robot having a language interaction function may implement speech interaction with a user through the audio component, etc.
The window wiping robot 100 may also include a cleaning component. The cleaning component may include a water storage tank, cleaning cloth, or a brush, etc. In an optional embodiment, water in the water storage tank is sucked by a water suction pump and evenly drips on the cleaning cloth, or water in the water storage tank drips on the cleaning cloth directly; or water in the water storage tank is atomized by an atomizer to form a water mist which is sprayed against a surface to be cleaned to soften dust.
In the present embodiment, the one or more memories 103 are configured primarily to store one or more computer instructions that are executable by the one or more processors 102 to cause the one or more processors 102 to control the window wiping robot 100 to implement corresponding functions and perform corresponding actions or tasks. In addition to storing computer instructions, the one or more memories 103 may be configured to store various other data to support operations on the window wiping robot 100. Examples of such data include instructions for any application or method operated on the window wiping robot 100.
The one or more memories 103 may be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as a static random access memory (SRAM), an electrically erasable programmable read-only memory (EEPROM), an erasable programmable read-only memory (EPROM), a programmable read-only memory (PROM), a read-only memory (ROM), a magnetic memory, a flash memory, a magnetic disk, or an optical disk.
The one or more processors 102, which may be regarded as a control system of the window wiping robot 100, may be configured to execute the computer instructions stored in the one or more memories 103 to control the window wiping robot 100 to implement corresponding functions and to perform corresponding actions or tasks. It should be noted that when the window wiping robot 100 is in different scenarios, the functions to be implemented and the actions or tasks to be performed thereby will be different. Accordingly, the computer instructions stored in the one or more memories 103 may vary, and execution of different computer instructions by the one or more processors 102 may control the window wiping robot 100 to implement different functions and perform different actions or tasks.
In the present embodiment, the window wiping robot 100 may move autonomously and perform a window wiping task on the basis of the autonomous movement. In the present embodiment, the processor 102 executes the computer instructions in the memory 103 to control the window wiping robot 100 to spin to detect a boundary of glass to be cleaned when the window wiping robot 100 needs to perform a window wiping task. Further, if the window wiping robot 100 detects the boundary of the glass to be cleaned during spinning, the window wiping robot 100 is controlled to perform the window wiping task along the detected boundary. In the embodiments of the present disclosure, for ease of description and distinction, the boundary of the glass to be cleaned, which is detected by the window wiping robot 100 during spinning, is defined as a first boundary. With regard to a glass window with a frame, the first boundary may be any frame of the glass window to be cleaned. With regard to a glass window without a frame, the first boundary may be either edge of the glass window to be cleaned. The window wiping robot 100 performing the window wiping task along the detected first boundary means that the window wiping robot 100 moves forward along the first boundary and wipes the glass window to be cleaned with the cleaning component (e.g., cleaning cloth) thereof during the movement. The window wiping robot 100 may be spaced from or in close contact with the first boundary during forward movement along the first boundary. When the window wiping robot 100 performs the window wiping task along the first boundary, the distance from the first boundary may be set according to the performance of the window wiping robot 100. It is theorized that when the window wiping robot 100 performs the window wiping task along the first boundary, it is advantageous to improve the cleaning effect of the boundary when the window wiping robot abuts against the first boundary. Accordingly, if the window wiping robot 100 does not detect a first boundary of the glass window to be cleaned during spinning, the processor 102 controls the window wiping robot 100 to perform the window wiping task in a set cleaning mode in any direction. In the embodiments of the present disclosure, the cleaning mode means that the window wiping robot 100 performs the window wiping task according to a set cleaning route. The cleaning mode includes: at least one of a bow-shaped cleaning mode (shown in
In the present embodiment, when a window wiping task needs to be performed, the window wiping robot firstly spins to detect a boundary of a glass window to be cleaned. If the boundary of the glass window to be cleaned is detected during spinning, the window wiping robot performs the window wiping task directly along the boundary. The cleaning mode may save the boundary detection time and help to improve the cleaning efficiency when starting to perform the window wiping task without detecting the boundary up, down, left, and right.
It should be noted that different implementations may be used to determine whether the window wiping robot 100 needs to perform the window wiping task for different application scenarios. Some common application scenarios are exemplified below.
Application Scenario 1: When a person daily uses a window wiping robot, the window wiping robot 100 is generally placed on a glass window to be cleaned, and then the window wiping robot 100 is triggered to power on, and the window wiping robot 100 performs a window wiping task after power-on. Optionally, the user may send a power-on instruction to the window wiping robot 100 via a remote control to trigger the window wiping robot 100 to power on. Or, the user may press a power-on button on the window wiping robot 100 to trigger the window wiping robot 100 to power on. Whichever power-on mode is employed, in Application Scenario 1, the processor 102 of the window wiping robot 100 determines that a window wiping task needs to be performed upon detecting the power-on instruction.
Application Scenario 2: In some application scenarios, the window wiping robot 100 may fail during the window wiping task, resulting in loss of previous data. In order to facilitate being able to continue the window wiping task in a correct manner, the window wiping robot 100 needs to re-determine a boundary of the glass window to be cleaned. In this application scenario, the window wiping robot 100 determines that a window wiping task needs to be performed when detecting state recovery. For example, when the window wiping robot 100 temporarily shuts down and then restarts due to failure, the processor 102 of the window wiping robot 100 determines that a window wiping task needs to be performed when a restart instruction is detected.
Application Scenario 3: In everyday life, after the window wiping robot has completed a task of cleaning one glass window, people often pick up the window wiping robot from the cleaned glass window and re-place it on another glass window to be cleaned, and the window wiping robot starts to perform the window wiping task on the glass window onto which the window wiping robot is put down. Based on this, when detecting that the window wiping robot 100 is re-placed onto the glass window, the processor 102 determines that the window wiping task needs to be performed by the window wiping robot 100.
Optionally, in Application Scenario 3, a contact sensor, a reflective optical coupler, an inertial sensor, or the like may be provided on the window wiping robot 100 to detect whether the window wiping robot 100 is picked up and re-put down during use. For example, the bottom of a base or rollers of the window wiping robot 100 may be provided with a contact sensor for detecting whether the window wiping robot 100 is moved and suspended under the control of the one or more processors 102, and also for determining whether the window wiping robot 100 returns to the ground. Or, a reflective optical coupler may be installed at the bottom of the window wiping robot 100, and the reflective optical coupler emits a beam that may be reflected from the ground, through which the operation of the window wiping robot 100 being moved or suspended and then returned to the glass window may be detected. The one or more processors 102 are triggered to initiate a repositioning function when the contact sensor or the reflective optical coupler detects that the window wiping robot 100 is re-placed onto the glass window. As another example, an inertial sensor, such as an acceleration sensor, is installed on the machine body 101 of the window wiping robot 100 to detect whether the window wiping robot 100 is dragged with a wide range, thereby determining that the window wiping robot 100 needs to perform a window wiping task when the dragging of the window wiping robot 100 is stopped.
Further, in some embodiments, a rotation direction and a rotation angle of the window wiping robot 100 may be preset. The preset rotation direction may be a counterclockwise rotation or a clockwise rotation, and in the present embodiment, the specific value of the rotation angle is not limited, and may be any angle of 0° to 360°. For example, the preset rotation angle may be, but is not limited to, 30°, 60°, 90°, 180°, or 360°. Based on this, when determining that the window wiping robot 100 needs to perform a window wiping task, the one or more processors 102 may control the window wiping robot 100 to rotate for a preset angle at a current position in a preset rotation direction. Or, when determining that the window wiping robot 100 needs to perform a window wiping task, the one or more processors 102 may control the window wiping robot 100 to randomly move for a certain distance and rotate for a preset angle at an arrived position in a preset rotation direction. Or, when determining that the window wiping robot 100 needs to perform a window wiping task, the one or more processors 102 may control the window wiping robot 100 to move for a certain distance in a preset moving direction and rotate for a preset angle at an arrived position in a preset rotation direction. The preset moving direction may be forward movement, backward movement, left movement, or right movement, etc. or other moving directions. Further, a movement distance of the window wiping robot 100 may be a preset distance, and the specific value thereof is not limited. A random number may also be generated for the processor 102 according to the current time, and a random distance is determined based on the random number.
In other embodiments, as shown in
The boundary detector may be implemented in various forms. For example, the boundary detector may be a guard plate, a ball head, a vision sensor, or a distance sensor, etc. Further, the vision sensor may be a camera, a laser image collector, etc. The distance sensor may be an infrared distance sensor, a laser distance sensor, or an ultrasonic sensor, etc. Depending on the shape of the glass window to be cleaned, the implementation of the boundary detector adapted to the shape of the glass window to be cleaned may vary. The boundary detector is implemented differently, and when the window wiping robot 100 detects the boundary of the glass window to be cleaned, the state change of the boundary detector occurs differently. The following illustrates:
For example, as shown in
As another example, as shown in
As another example, if the boundary detector is a vision sensor, the vision sensor continuously collects a surrounding environment image during the spinning of the window wiping robot 100, the processor 102 continuously judges whether the window wiping robot 100 is in contact with the boundary of the glass window to be cleaned according to the environment image collected by the vision sensor, and determines that the window wiping robot 100 detects the first boundary of the glass window to be cleaned if the judgment result is yes. The window wiping robot 100 provided with the vision sensor is adapted to clean various forms of glass windows, such as glass windows with frames or glass curtain walls without frames.
As another example, if the boundary detector is a distance sensor, the distance sensor continuously measures a distance between the window wiping robot 100 and each boundary of the glass window to be cleaned during the spinning of the window wiping robot 100, the processor 102 continuously judges whether the measured distance is smaller than or equal to a preset distance threshold, and it is determined that the first boundary of the glass window to be cleaned is detected by the window wiping robot 100 if the judgment result is yes. The preset distance threshold may be flexibly set according to the measurement accuracy of the distance sensor, and is not limited herein. The window wiping robot 100 provided with the distance sensor is adapted to clean a glass window with a frame.
Further, as shown in
Further, considering that the window wiper wiping robot 100 detects the first boundary A, the window wiping robot 100 may not be able to directly adjust the forward direction thereof to be parallel to the first boundary A from a position where the first boundary A is detected due to space limitation. Based on this, in the embodiments of the present disclosure, the one or more processors 102 may also determine an included angle between the forward direction of the window wiping robot 100 and the first boundary A when the first boundary A is detected, and judge whether the included angle is smaller than a preset angle threshold. As shown in
Accordingly, as shown in
Optionally, a visual sensor on the window wiping robot 100, such as a camera, may be used to capture an image in front of the window wiping robot 100. The image includes a first boundary A. Then, an included angle between the forward direction of the window wiping robot 100 when the first boundary A is detected and the first boundary A may be calculated according to a capturing angle of the image and an angle of the first boundary A in the image.
Optionally, as shown in
Further, the one or more processors 102 also detect a distance between the window wiping robot 100 and a fourth boundary D of the glass window to be cleaned while controlling the window wiping robot to continue to perform the window wiping task in the set cleaning mode. Further, as shown in
Further, for a narrow glass window having a width greater than the width of the window wiping robot 100, but less than twice the width of the window wiping robot 100, as shown in
In step 1, when the window wiping robot 100 determines that a window wiping task needs to be performed, the one or more processors 102 control the window wiping robot 100 to spin, and the window wiping robot 100 detects a first boundary A of a glass window to be cleaned during the spinning process. (As shown in
In step 2, the one or more processors 102 may control the window wiping robot 100 to move forward along the first boundary A in the adjusted forward direction, and control the window wiping robot to move reversely along the first boundary A when moving to a second boundary B of the glass window to be cleaned until the window wiping robot 100 moves to a third boundary C of the glass window to be cleaned. (As shown in
In step 3, when the window wiping robot 100 moves to the third boundary C, the one or more processors 102 control the window wiping robot 100 to differentially travel to a fourth boundary D, and control the window wiping robot 100 to continue to perform the window wiping task along the fourth boundary D in a forward direction parallel to the fourth boundary D. (As shown in
It should be noted that in
At 201, if a window wiping task needs to be performed, a window wiping robot is controlled to spin to detect a boundary of a glass window to be cleaned.
At 202, if a first boundary of the glass window to be cleaned is detected during spinning of the window wiping robot, the window wiping robot is controlled to perform the window wiping task along the first boundary.
In the present embodiment, the window wiping robot may move autonomously and perform a window wiping task on the basis of the autonomous movement. The description about the implementation form and appearance form of the window wiping robot may be referred to the related contents of the above embodiments. In step 201, when a window wiping robot needs to perform a window wiping task, the window wiping robot is controlled to spin to detect a boundary of glass to be cleaned. Further, if the window wiping robot detects the boundary of the glass to be cleaned during spinning, the window wiping robot is controlled to perform the window wiping task along the detected boundary in step 202. In the embodiments of the present disclosure, for ease of description and distinction, the boundary of the glass to be cleaned, which is detected by the window wiping robot during spinning, is defined as a first boundary. The definition of the first boundary and the description of the window wiping robot performing the window wiping task along the detected first boundary may be referred to the above contents, and will not be repeated herein.
Accordingly, if the window wiping robot does not detect a first boundary of the glass window to be cleaned during spinning, the processor on the window wiping robot controls the window wiping robot to perform the window wiping task in a set cleaning mode in any direction. In the embodiments of the present disclosure, the cleaning mode means that the window wiping robot performs the window wiping task according to a set cleaning route. The cleaning mode includes: at least one of a bow-shaped cleaning mode (shown in
In the present embodiment, when a window wiping task needs to be performed, the window wiping robot firstly spins to detect a boundary of a glass window to be cleaned. If the boundary of the glass window to be cleaned is detected during spinning, the window wiping robot performs the window wiping task directly along the boundary. The cleaning mode can save the boundary detection time and help to improve the cleaning efficiency when starting to perform the window wiping task without detecting the boundary up, down, left, and right.
It should be noted that different implementations may be used to determine whether the window wiping robot needs to perform the window wiping task for different application scenarios. Some common application scenarios are exemplified below.
In Application Scenario 1, the processor of the window wiping robot determines that a window wiping task needs to be performed upon detecting a power-on instruction.
In Application Scenario 2, the processor of the window wiping robot determines that a window wiping task needs to be performed upon detecting a restart instruction.
In Application Scenario 3, the processor of the window wiping robot determines that the window wiping robot needs to perform a window wiping task upon detecting that the window wiping robot is re-placed onto the glass window. A specific implementation of how to determine that the window wiping robot is re-placed onto the glass window may be referred to the related contents of the above embodiments regarding Application Scenario 3, and will not be repeated herein.
Further, in some embodiments, a rotation direction and a rotation angle of the window wiping robot 100 may be preset. The preset rotation direction may be a counterclockwise rotation or a clockwise rotation, and in the present embodiment, the specific value of the rotation angle is not limited, and may be any angle of 0° to 360°. For example, the preset rotation angle may be, but is not limited to, 30°, 60°, 90°, 180°, or 360°. Based on this, an implementation of step 201 is as follows. When it is determined that the window wiping robot needs to perform a window wiping task, the window wiping robot may be controlled to rotate for a preset angle at a current position in a preset rotation direction. Or, when it is determined that the window wiping robot needs to perform a window wiping task, the window wiping robot may be controlled to randomly move for a certain distance and rotate for a preset angle at an arrived position in a preset rotation direction. Or, when it is determined that the window wiping robot needs to perform a window wiping task, the window wiping robot may be controlled to move for a certain distance in a preset moving direction and rotate for a preset angle at an arrived position in a preset rotation direction. The preset moving direction may be forward movement, backward movement, left movement, or right movement, etc. or other moving directions.
In other embodiments, the window wiping robot may further include a boundary detector for detecting a boundary of the glass window to be cleaned during the spinning of the window wiping robot. The boundary detector may be provided either inside the machine body or on a surface of the machine body. Based on this, the state of the boundary detector of the window wiping robot may be detected during the spinning of the window wiping robot. If the state of the boundary detector changes, it is determined that a first boundary of the glass window to be cleaned is detected. A position of the first boundary is a position on the glass window to be cleaned where the state of the boundary detector changes.
Further, the boundary detector may be implemented in various forms. For example, the boundary detector may be a guard plate, a ball head, a vision sensor, or a distance sensor, etc. Further, the vision sensor may be a camera, a laser image collector, etc. The distance sensor may be an infrared distance sensor, a laser distance sensor, or an ultrasonic sensor, etc. Depending on the shape of the glass window to be cleaned, the implementation of the boundary detector adapted to the shape of the glass window to be cleaned may vary. The boundary detector is implemented differently, and when the window wiping robot detects the boundary of the glass window to be cleaned, the state change of the boundary detector occurs differently. The following illustrates:
For example, as shown in
As another example, as shown in
As another example, if the boundary detector is a vision sensor, the vision sensor continuously collects a surrounding environment image during the spinning of the window wiping robot, the processor continuously judges whether the window wiping robot is in contact with the boundary of the glass window to be cleaned according to the environment image collected by the vision sensor, and determines that the window wiping robot detects the first boundary of the glass window to be cleaned if the judgment result is yes. The window wiping robot provided with the vision sensor is adapted to clean various forms of glass windows, such as glass windows with frames or glass curtain walls without frames.
As another example, if the boundary detector is a distance sensor, the distance sensor continuously measures a distance between the window wiping robot and each boundary of the glass window to be cleaned during the spinning of the window wiping robot, the processor continuously judges whether the measured distance is smaller than or equal to a preset distance threshold, and it is determined that the first boundary of the glass window to be cleaned is detected by the window wiping robot if the judgment result is yes. The preset distance threshold may be flexibly set according to the measurement accuracy of the distance sensor, and is not limited herein. The window wiping robot provided with the distance sensor is adapted to clean a glass window with a frame.
Further, as shown in
Further, considering that the window wiper wiping robot detects the first boundary A, the window wiping robot may not be able to directly adjust the forward direction thereof to be parallel to the first boundary A from a position where the first boundary A is detected due to space limitation. Based on this, an optional implementation of controlling the window wiping robot to adjust a forward direction thereof to be parallel to a first boundary A is as follows. An included angle between the forward direction of the window wiping robot and the first boundary A when the first boundary A is detected is determined, and it is judged whether the included angle is smaller than a preset angle threshold. As shown in
Accordingly, as shown in
Optionally, as shown in
Further, the processor also detects a distance between the window wiping robot and a fourth boundary D of the glass window to be cleaned while controlling the window wiping robot to continue to perform the window wiping task in the set cleaning mode. Further, as shown in
Further, for a narrow glass window having a width greater than the width of the window wiping robot, but less than twice the width of the window wiping robot, an implementation of the window wiping robot performing the window wiping task may be described with reference to steps 1 to 3 above in conjunction with
Accordingly, the embodiments of the present disclosure also provide a computer-readable storage medium, storing computer instructions.

It is also to be noted that terms “include”, “contain” or any other variants thereof are intended to include nonexclusive inclusions, thereby ensuring that a commodity or system including a series of elements not only includes those elements but also includes other elements which are not clearly listed or further includes elements intrinsic to the commodity or the system. Under the condition of no more restrictions, an element defined by statement “including a/an” does not exclude existence of another element which is the same in a commodity or system including the element.
The above is only the embodiment of the present disclosure and not intended to limit the present disclosure. Those skilled in the art may make various modifications and variations to the present disclosure. Any modifications, equivalent replacements, improvements and the like made within the spirit and principle of the present disclosure shall fall within the scope of the claims of the present disclosure.
