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 garden tool includes a prime mover, a housing, a power source, and a door. The housing defines a power source compartment. The housing also defines a first aperture and a second aperture each in communication with the power source compartment. The power source is configured to provide power to the prime mover. The power source is removably receivable in the power source compartment. The door is configured to move between a closed position in which the first aperture is closed and an open position in which the first aperture is open. The second aperture is configured to provide fluid communication between the power source compartment and an external environment for draining fluid from the power source compartment.

Abstract: A communication system may include a robotic garden tool, a first external device, and a server device. The first external device receives a user input of a selected lawn pattern, and generates, on a display of the first external device, a three-dimensional representation of a lawn surface based on the selected lawn pattern. The first external device transmits the lawn pattern information corresponding to the selected lawn pattern to a server device and to the robotic garden tool. The server device transmits the lawn pattern information to a second external device. The robotic garden tool receives the lawn pattern information from the first external device, and controls an operation of the robotic garden tool on a real-world lawn based on the lawn pattern information to generate the selected lawn pattern on the real-world lawn.

CPC classification number: A01D34/74 , A01D34/64 , A01D34/008
Abstract: A robotic garden tool including a deck, a blade motor configured to rotate a blade about a blade axis, and a mount axially movable with respect to the deck along the blade axis. The garden tool also includes a worm shaft mounted for rotation with respect to the deck about a worm axis, the work shaft forming a threaded interface with the mount such that rotation of the worm shaft about the worm axis causes the mount to move axially with respect to the deck. The garden tool also includes a manual actuator configured to move with respect to the deck in response to receiving a manual actuation force by an operator, where the manual actuator is in operable communication with the worm shaft such that movement of the manual actuator with respect to the deck causes the worm shaft to rotate about the worm axis.

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.
