    Abstract: A method of turning a robotic garden tool in the presence of an object, where the robotic garden tool includes a body with a first end and a second end opposite the first end. The method includes moving the robotic garden tool in a first direction of travel with the first end serving as the leading end, stopping the robotic garden tool at a first location spaced a predetermined distance from the object, rotating the robotic garden tool when in the first location, and moving the robotic garden tool away from the first location in a second direction of travel with the second end serving as the leading end.

    Abstract: A robotic garden tool may include a sensor configured to receive a wireless signal from a docking station. The robotic garden tool may also include an electronic processor configured to control the robotic garden tool to move toward the docking station by controlling the robotic garden tool to move in a first approximately straight line, and repeatedly determining a strength of the wireless signal. In response to determining that the strength of the wireless signal has begun decreasing as the robotic garden tool continues to move in the first approximately straight line, the electronic processor may control the robotic garden tool to stop moving in the first approximately straight line and turn to move in a predetermined manner to move in a second approximately straight line such that the robotic garden tool continues to move toward the docking station.

    Abstract: An augmented reality device may include a camera configured to capture image data. The augmented reality device may also include a projector, and an electronic processor coupled to the camera and to the projector. The electronic processor may be configured to identify a power tool to be used by a user of the augmented reality device. The electronic processor may be further configured to identify, based on the image data captured by the camera, a work piece on which an operation of the power tool is intended to be performed. The electronic processor may be further configured to control the projector to project an indication that indicates a location on the work piece at which the operation of the power tool is intended to be performed.

    Abstract: A theft prevention system includes a robotic garden tool that includes a housing, and a set of wheels coupled to the housing and configured to rotate to propel the robotic garden tool on an operating surface. The robotic garden tool further includes at least one wheel motor coupled to one or more wheels of the set of wheels to drive rotation of the one or more wheels. The robotic garden tool further include a first electronic processor configured to detect a potential theft event associated with the robotic garden tool. The first electronic processor may be further configured to engage in an anti-theft action in response to detecting the potential theft event. The anti-theft action may include ceasing at least one operation of the robotic garden tool until the first electronic processor receives a code indicating that the potential theft event should be ignored.

    Abstract: A robotic garden tool for use with a boundary wire producing an electromagnetic field, the robotic garden tool including a body, one or more wheels coupled to the body, a working tool coupled to the body, and a first sensor set coupled to the body. Where the first sensor set includes a first sensor configured to detect the orientation and magnitude of the electromagnetic field along a first detection axis, and a second sensor configured to detect the orientation and magnitude of the electromagnetic field along a second detection axis and output a signal representative thereof. The garden tool also including a controller in operable communication with the first sensor set, where the controller is configured to determine the relative location of the boundary wire with respect to the first sensor set based at least in part on the signals output by the first and second sensors.

    Abstract: A robotic garden tool may include an object detection sensor. Object detection data from the object detection sensor may indicate a respective position of each of one or more objects with respect to the robotic garden tool. The robotic garden tool may be configured to execute a speed control algorithm that may include determining, based on the object detection data, whether any objects are present within a detection area of the object detection sensor. The speed control algorithm also may include adjusting a speed of the robotic garden tool and/or a travel direction of the robotic garden tool based on whether and where any objects are detected within the detection area.
