Abstract: A robotic garden tool may include a first sensor configured to sense an electromagnetic signal from a boundary cable installed on an operating surface, and a second sensor configured to sense a first anchor installed on the operating surface. The robotic garden tool may also include an electronic processor configured to control, based on first sensor data received from the first sensor, operation of at least one wheel motor to control movement of the robotic garden tool such that the robotic garden tool remains within a boundary defined by the boundary cable. The electronic processor may also be configured to, in response to receiving second sensor data from the second sensor that indicates a sensing of the first anchor, control operation of the at least one wheel motor to control movement of the robotic garden tool in a first predetermined manner.
