The communication part 210 is, for example, a wireless communication module for connecting to a network NW or communicating directly with another terminal device or the like. The communication part 210 performs wireless communication on the basis of Wi-Fi, DSRC (Dedicated Short-Range Communications), Bluetooth (Registered Trademark), or other communication standards.
The information management part 220 manages information that is provided by the terminal device 100 or the movable body 300. For example, the information management part 220 stores the information that is provided by the terminal device 100 or the movable body 300 in the storage part 250. The information management part 220 provides the information stored in the storage part 250 (information obtained based on the information stored in the storage part 250) to the terminal device 100 or the movable body 300.
The command part 230 provides a command to the movable body 300 on the basis of the information that is provided by the terminal device 100. The command is a command regarding a direction in which the movable body 300 proceeds, the height of the movable body 300, and the like. Further, the command may include a speed, a route, a trajectory, and the like when the movable body proceeds to a destination.
The movable body 300 includes, for example, a base body 302, a wheel 304R and a wheel 304L that are attached to the base body 302, a cushion-like seat part 306 on which a passenger is seated, a lifting mechanism 308 (refer to
The wheel 304R and the wheel 304L are an example of a “travel part”. The seat part 306 is an example of a “boarding part”. The present embodiment is described using an example that utilizes the movable body 300 as shown in
The wheel 304R is provided on a +Y direction side of the movable body 300. The wheel 304L is provided on a −Y direction side of the movable body 300. The wheel 304R and the wheel 304L are driven by the motor. The seat part 306 is arranged above the base body 302. An upper surface of the seat part 306 is a seat surface that supports the hip of the passenger from below. The seat part 306 is supported by the base body 302 via the lifting mechanism 308. Details of the first support part 310 and the second support part 320 are described below.
The operation part 330 includes an operation element for the worker to control an operation of the movable body 300. For example, the operation element is an operation element for controlling the speed of the movable body 300, a braking operation, and the lifting mechanism 308.
The first support part 310 is provided on an end part in the +X direction of the seat part 306, extends in a ground direction, and supports the movable body 300 as needed. The second support part 320 is provided on an end part in the −X direction of the seat part 306, extends in the ground direction, and supports the movable body 300 as needed.
The first support part 310 and the second support part 320 are controlled, for example, by a control mechanism 322 (refer to
For example, when the worker boards the movable body 300, the lifting mechanism 308 controls the seat part 306 to a lower position on the basis of a control of the control device 380. In accordance with the height of the seat part 306, the ground contact part of the first support part 310 and the second support part 320 is controlled to be located on the ground.
Thereby, for example, the stability when the worker boards the movable body 300 is ensured. When the movable body 300 travels, the first support part 310 and the second support part 320 may be controlled such that the ground contact part is not located on the ground. Thereby, the travel performance of the movable body 300 is improved.
The first support part 310 and the second support part 320 may have a stretchable or retractable configuration in place of the functional configuration described above. In this case, when the seat part 306 is controlled, the first support part 310 and the second support part 320 may extend and be located on the ground, or the first support part 310 and the second support part 320 may emerge from a storage part and be located on the ground.
The external sensor 350 is, for example, a camera, a laser range finder, an infrared sensor, or the like, and is a functional configuration capable of detecting a situation and an object around the movable body 300. The external sensor 350 is set, for example, at a position where the periphery (for example, the front) of the movable body 300 can be imaged. For example, the external sensor 350 is provided on an end portion of the operation part 330 on the +X direction side or the like. In the following description, as an example, the external sensor 350 is a camera.
The communication device 352 is, for example, a wireless communication module for connecting to the network NW or communicating directly with another terminal device or the like. The communication device 352 performs wireless communication on the basis of Wi-Fi, DSRC, Bluetooth, or other communication standards.
The vehicle sensor 354 is a sensor that detects the speed, the acceleration, the angular speed around the vertical axis, or the like of the movable body 300.
The GNSS receiver 356 measures the self-position on the basis of radio waves arriving from a GNSS satellite (for example, a GPS satellite). The GNSS receiver 356 outputs the positioning result to the control device 380.
The control device 380 includes, for example, a recognition part 382, an acquisition part 384, an information-processing part 386, a first control part 388, and a second control part 390. These functional configurations are implemented, for example, by a processor such as a CPU as hardware executing a program (software). Some or all of these functional configurations may be implemented by hardware (a circuit part including circuitry) such as an LSI, an ASIC, a FPGA, or a GPU or may be implemented by software and hardware in cooperation. The program may be stored in advance in a storage device (a storage device including a non-transitory storage medium) such as a HDD or a flash memory. The program may be stored in a removable storage medium (a non-transitory storage medium) such as a DVD or a CD-ROM and be installed in the storage device by the storage medium being mounted on a drive device.
The recognition part 382 recognizes an object around the movable body 300 on the basis of an image captured by the external sensor 350. The recognition part 382 recognizes, for example, the presence or absence of an obstacle, the situation of a road on which the movable body travels, the kind of an object that is present in the vicinity, the position of the object, and the like.
The acquisition part 384 acquires information that is acquired by the communication device 352 or acquires information that is acquired by the vehicle sensor 354 or the GNSS receiver 356. The acquisition part 384 acquires, from the terminal device 100 that is carried by the worker and that receives information which is input by the worker in accordance with the work task, information based on input information which is input by the worker in accordance with the work task. Details of the input information will be described later.
The information-processing part 386 manages the information that is acquired by the acquisition part 384 or controls each item of equipment (equipment other than the equipment as a control target of the first control part 388 and the second control part 390) included in the movable body 300.
The first control part 388 controls the motor of the movable body 300 to cause the movable body 300 to travel.
The first control part 388 causes the movable body 300 to travel on the basis of an operation of the operation part 330 or a command of the management device 200.
The second control part 390 controls the lifting mechanism 308 or the control mechanism 322. The second control part 390 controls the lifting mechanism 308 on the basis of an operation of the operation part 330 or a command of the management device 200.
The second control part 390 controls the height of the seat part 306 on the basis of the information that is acquired by the acquisition part 384.
The worker boards the movable body 300, moves within a predetermined facility, and performs a work task. The facility is, for example, a facility having a predetermined size such as a substation but is not limited thereto. The work task is, for example, a work task in which a worker performs confirmation, an operation, or treatment of the equipment in a facility or the like. In the following description, as an example, a worker performs a work task of confirming the information indicated by an instrument at a facility such as a substation.
In a case where the worker boards a designated movable body 300 and, for example, arrives near the instrument 1, an image IM is displayed on the display part of the terminal device 100.
The image IM may be displayed when the worker performs a predetermined operation of the terminal device 100. Alternatively, the terminal device 100 may display the image IM on the display part when the movable body 300 arrives near the instrument 1 on the basis of the position information of the movable body 300.
The image IM includes an icon IC1, an icon IC2, and an icon IC3. The icon IC1 is a button operated when a work task 1 is started. The icon IC2 is an icon in which the information indicated by the instrument 1 is input. For example, in a case where the icon IC1 is operated, when the worker operates the icon IC2, a numeric keypad or the like is displayed on the display part. The worker operates the numeric keypad and inputs the information indicated by the instrument 1. When the worker operates the icon IC3, the information input to the icon IC2 is transmitted to the management device 200.
Information indicating that the icon IC1, the icon IC2, or the icon IC3 is operated is an example of input information. Information indicating that the icon IC1 is operated is an example of “information indicating that the work task has started”. Information that is indicated by the instrument 1 and that is input to the icon IC2 is an example of “information that is indicated by equipment” or “information indicating that the worker has confirmed information that is indicated by equipment which is provided at the workplace”. Information indicating that the icon IC3 is operated is an example of “information indicating that the work task has been completed” or “information indicating that the worker has confirmed the information indicating equipment which is provided at the workplace”. “Information based on input information” is information (for example, information which commands that the height of the seat part 306 is controlled) transmitted to the movable body 300 by the management device 200 in response to the acquisition of the input information described above by the management device 200.
In response to the operation of the icon, the height of the seat part 306 of the movable body 300 is automatically adjusted as shown in
In the present embodiment, for example, when the icon IC1 is operated, the seat part 306 of the movable body 300 is automatically adjusted to a height in accordance with the instrument 1.
Further, when the worker operates the icon IC3, the height of the seat part 306 is automatically adjusted to the height before the icon IC1 is operated. Thereby, the worker can promptly proceed to the next work task.
The above-described process in which the height is adjusted may be started on the condition that the worker has performed a predetermined operation in addition to the operation of the icon. The predetermined operation is, for example, an operation of the operation part 330 of the movable body or an operation of the terminal device 100. The predetermined operation is, for example, a simpler operation than an operation in which the worker operates the operation part 330 and adjusts the height of the seat part 306 as usual.
Next, the management device 200 transmits a command (information based on the input information) to adjust the height to the movable body 300 when the start information is acquired (Step S102). This command includes information indicating how much the height is to be adjusted. The management device 200 transmits the command, for example, with reference to relevance information in which the height of the instrument is associated with the adjustment degree of the height. The control device 380 of the movable body 300 controls the seat part 306 to a height suitable for the height of a target (instrument) of the work task on the basis of the command. Thereby, the height of the seat part 306 of the movable body 300 is adjusted to a height in accordance with the work task. That is, the height of the movable body 300 is adjusted to a position where the worker can easily view the instrument (a position where the work task can be easily performed).
Next, the movable body 300 adjusts the height of the seat part 306 on the basis of the command in Step S102 (Step S104) and transmits, to the management device 200, information indicating that the adjustment of the height has been completed after the adjustment is completed (Step S106).
When the information transmitted in Step S106 is acquired, the management device 200 transmits the acquired information to the terminal device 100 (Step S108). When the information transmitted in Step S108 is acquired, the terminal device 100 controls the input of the icon IC2 from an inactive state to an active state (Step S110).
The inactive state is a state in which the terminal device 100 does not receive information being input to the icon IC2. The active state is a state in which the terminal device 100 accepts information being input to the icon IC2.
After the process of Step S110, the terminal device 100 accepts an input of information to the icon IC2 (Step S112) and transmits the accepted information (for example, information indicated by the instrument) to the management device 200 (Step S114). Next, the management device 200 registers the information transmitted in Step S114 to the instrument information 256 (Step S116). Thereby, the management device 200 deems that the work task with respect to the target equipment has been completed.
When the work task has been completed, the management device 200 transmits information indicating that the work task has been completed to the terminal device 100 and the movable body 300 (Steps S118 and S120). In a case where the movable body 300 acquires the information indicating that the work task has been completed, the height of the seat part 306 is adjusted to a predetermined height or a height before the height is adjusted in Step S102 (Step S122). Then, after the height has been adjusted, in order to perform the next work task, the movable body 300 travels toward a position of the next work target automatically or on the basis of the operation of the worker. At this time, the movable body 300 may use a speaker or the like and report, by way of speech, the information (information of the kind of work task, target equipment, a movement direction, and the like) regarding the next work task on the basis of the information acquired from the management device 200.
The movable body 300 may lower the height of the seat part 306 when acquiring information that is indicated by the equipment and/or information indicating that the worker has confirmed the information indicating the instrument which is provided at the workplace (for example, in a case where information indicating the instrument is input to the terminal device 100 or in a case where the information indicated by the instrument is transmitted to the management device 200) in place of (or in addition to) the information indicating that the work task has been completed.
In this way, the movable body 300 adjusts the height of the movable body 300 in accordance with the progress of the work task, and thereby, convenience to the worker is improved.
According to the first embodiment described above, the control device 380 controls the height of the seat part 306 on the basis of the information based on input information that is input by the worker in accordance with the work task from the terminal device 100, and thereby, convenience to the worker is improved.
The above embodiment is described using an example in which the height of the seat part 306 is controlled on the basis of the information based on the input information. Alternatively, the movable body 300 may control the height of the seat part 306 in a case where the information based on the input information is acquired and further a predetermined condition is satisfied (or in a case where a predetermined condition is satisfied in a state where the information based on the input information is not acquired).
The predetermined condition is, for example, some or all of the following conditions (1) to (6).
(1) The worker performs a predetermined gesture (refer to <First modified example>).
(2) A code which is provided on a work target and which becomes a trigger of an adjustment of height is recognized by the control device 380, the terminal device 100, or the management device 200 (refer to <Second modified example>).
(3) The control device 380, the terminal device 100, or the management device 200 acquires predetermined information from the target (refer to <Second modified example>).
(4) The movable body 300 is present at a predetermined position relative to the work target. The above (4) is, for example, that the movable body 300 is present at a predetermined distance (or a position set relative to the work target) from the work target.
(5) The movable body 300 or the management device 200 recognizes a position of the work target in real time on the basis of an image (refer to <Third modified example>).
(6) A predetermined mechanism which is provided on the work target is operated (refer to <Fourth modified example>).
Hereinafter, a first modified example is described. In the first modified example, the height of the seat part 306 of the movable body 300 is adjusted by a predetermined gesture (or motion) of the worker. Hereinafter, the difference from the first embodiment is mainly described.
The movable body 300 transmits the detection result that is provided by the detection device 400 to the management device 200. The management device 200 estimates the motion of the worker on the basis of the detection result and commands the movable body 300 in accordance with the estimated motion. For example, as shown in
Further, for example, in a case where the worker lowers an arm, the management device 200 commands the movable body 300 to lower the height of the seat part 306. Thereby, the worker can easily adjust the height of the seat part 306.
The above embodiment is described using an example in which the management device 200 commands the movable body 300 to adjust the height of the seat part 306; however, alternatively, the movable body 300 may estimate the motion on the basis of the detection result of the detection device 400 and may adjust the height of the seat part 306 on the basis of the estimation result without intermediating the management device 200. A control part (for example, a CPU) included in the detection device 400 may estimate the motion on the basis of information provided by the IMU.
According to the first modified example described above, height adjustment that further reflects the worker's intention is performed.
As a result, the convenience to the user is further improved. In addition to (instead of) the gesture, the height of the seat part 306 may be controlled on the basis of the speech of the worker. In this case, the movable body 300 analyzes the speech that is input to a microphone or the like and controls the height of the seat part 306 on the basis of the analysis result.
Hereinafter, a second modified example is described. In the second modified example, the height of the seat part 306 is adjusted on the basis of information that is provided by a work target. Hereinafter, the difference from the first embodiment is mainly described.
The information that is provided by a work target is, for example, information regarding the adjustment of the height of the seat part 306 that is provided on the work target or that is transmitted to the work target. The information regarding the adjustment of the height is information indicating the height of the instrument, information indicating the height (or degree of operation) of the seat part 306, or information that embodies such information (for example, a QR code (registered trademark), a bar code, or the like).
The QR code may be imaged by a camera that is provided on the terminal device 100. In this case, the recognition of the height of the instrument by the decoding may be performed by the terminal device 100 or may be performed by another device.
The movable body 300 or the terminal device 100 may communicate with the instrument, the movable body 300 or the terminal device 100 may acquire information for adjusting the height of the seat part 306 acquired from the instrument, and may adjust the height of the seat part 306 on the basis of the acquired information.
According to the second modified example described above, the same advantage as that of the first embodiment is achieved.
Hereinafter, a third modified example is described. For example, the recognition part 382 recognizes the height of the instrument on the basis of an image that is imaged by the external sensor 350. Then, the second control part 390 may adjust the height of the seat part 306 on the basis of the height that is recognized by the recognition part 382. For example, the recognition part 382 recognizes the instrument or the height of the instrument on the basis of a learned model such as a neural network. The learned model is a model in which learning data associated with the image where the instrument is imaged and the position (or the height) of the instrument is learned.
According to the third modified example described above, the same advantage as that of the first embodiment is achieved.
Hereinafter, a fourth modified example is described. For example, in a case where a predetermined operation is performed on the instrument, the movable body 300 adjusts the height of the seat part 306. The predetermined operation is that a door that is provided on the instrument is opened or that a key that is provided on the instrument is operated from a locking condition to an unlocking condition.
According to the fourth modified example described above, the same advantage as that of the first embodiment is achieved.
Hereinafter, a fifth modified example is described. For example, the management device 200 may change the degree of adjustment of the height of the seat part 306 in accordance with the worker. For example, the management device 200 learns the worker's preference regarding the height adjustment and provides a command regarding the height adjustment to the movable body 300 on the basis of the learning result.
After the preference is set and after a set of work tasks are finished, the worker's preferences may be applied to the next set of work tasks (for example, a set of work tasks on the following day). For example, the management device 200 stores information in which worker's identification information and the worker's preference are associated with each other in the storage part 250 and understands the worker's preference with reference to this information.
The management device 200 may determine the degree of increase in the height of the seat part 306 in accordance with the worker on the basis of the body shape (for example, the body height) of the worker. For example, the management device 200 acquires the body height of the worker and adds 10 cm to the degree of adjustment of the height that is set in a default configuration in a case where the body height of the worker is higher than a reference body height by 10 cm.
