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 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: 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 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 robotic garden tool having a deck, a blade, a motor, and a blade height adjustment mechanism. The blade is movably coupled to the deck. The motor is configured to move the blade about an axis of rotation, and the axis of rotation defines an axial direction. The blade height adjustment mechanism includes a manual actuator configured to move in response to manual actuation by an operator. The manual actuator is operably coupled to a cam interface. The cam interface is disposed within a cylindrical volume defined circumferentially by the cam interface and bounded axially by upper and lower distal ends of the cam interface. The axis of rotation of the blade intersects the cylindrical volume. The blade is configured to move at least partially in the axial direction in response to movement of the manual actuator.
