Abstract: A charging control system includes a lawn mower that includes a battery and performs a lawn mowing work while traveling autonomously, and a charging station for charging the battery. The lawn mower includes a superimposing unit for superimposing, on a charging current, a current indicating period information for defining a shutoff period of supply power to be supplied from the charging station. The charging station includes a current detector for detecting the charging current, an information acquisition unit for acquiring period information based on a detection result of the current detector, a switch for shutting off the supply power, and a shutoff controller for controlling the operation of the switch. The shutoff controller releases the shutoff of supply of power to the lawn mower based on the period information acquired by the information acquisition unit. Therefore, the power consumption of the lawn mower can be reduced.

Abstract: A method includes identifying a first anchor of a plurality of anchors as an initiator and identifying multiple second anchors of the plurality of anchors as multiple responders, the plurality of anchors located in a service area to be traversed by a robot. The method also includes sending, to the initiator and the responders via a wireless side-link, ranging information and a command to start ultra-wideband (UWB) ranging. The method also includes receiving, from the initiator via the wireless side-link, pair-wise range measurements representing UWB range measurements between the initiator and the responders. The method also includes generating initial location values for the initiator and the responders based on the pair-wise range measurements and one or more geometric constraints imposed on the initiator and the responders. The method also includes estimating 3D coordinates of the initiator and the responders using the initial location values.

Abstract: A moving robot includes: a boundary signal detector configured to detect a proximity boundary signal generated in a proximity boundary area in which a portion of a first travel area and a portion of a second travel area are proximal to each other; and a controller configured to define a proximity boundary line based on the proximity boundary signal, and control the travelling unit such that the body performs a homing travel which indicates travelling along the proximity boundary line. The moving robot may be included in a system that includes boundary wires to define the first and second travel areas. The system may further include a docking unit to dock with and charge the moving robot.

Abstract: This application discloses a self-moving device, a method for adjusting a movement trajectory. The device includes a body, an image acquisition module, and a control circuit. The image acquisition module acquires an image in a traveling direction of the body. The control circuit fits, according to the image, a boundary corresponding to a working region in which the self-moving device is located. In response to the body moves toward the boundary and the body and the boundary meet a preset distance relationship, an angle relationship between the traveling direction of the body and the boundary is recognized according to the image, and the body is controlled to steer.

Abstract: A method for constructing a map for a mower includes: acquiring a preliminary map of a work region, two adjacent target points are used as first target points and are connected to form an initial connecting line; selecting a target point farthest from the initial connecting line as a second target point, and using a connecting line between the second target point and the first target points as to-be-processed connecting lines; selecting a third target point for each to-be-processed connecting line; when a condition is met, using connecting lines between the third target point and the target points at the two ends of the to-be-processed connecting line as new to-be-processed connecting lines and returning; retaining each of the third target points whose distance from a corresponding to-be-processed connecting line is greater than the first preset threshold as a map construction target point, and constructing a boundary map.

Abstract: Systems and techniques for detecting a difference in orientation between a lawn mower and a surface on which the mower is mowing, or between portions of such surface, based on one or more of sensor data or map data are discussed. The difference in orientation may then be used to control the lawn mower by, for example, raising a deck height or idling a blade speed, though other actuations are contemplated. In some examples, an amount the deck height is raised may be based on the difference in orientation. Based on a subsequent difference detected being at or below a threshold difference, the mower may return to previous operating conditions including, but not limited to, returning a blade speed to a previous blade speed and/or returning the deck height to a previous deck height, among other controls. Such techniques may prevent undercutting turf due to such differences.

Abstract: A method and system for fostering controlled growth of a turfgrass in a target area, includes: providing an autobot capable of automatically applying a UVC light treatment to the target grass area, wherein the target grass area comprises C4 turfgrass. The method and system includes coupling a UVC light subsystem to the autobot such that the UVC light subsystem is suspended above the C4 turfgrass within the target grass within a first predetermined range. Next, UVC light is generated by the UVC light subsystem with a wavelength within a second predetermined range. Subsequently, the UVC light is emitted from the UVC light subsystem to the C4 turfgrass at an intensity within a third predetermined range. And the UVC light is moved across the C4 turfgrass within the target grass area using the autobot at night at a speed within a fourth predetermined range.
