Patent abstract
A robotic mower home finding system includes a charging station connected to an outer boundary wire loop, and a vehicle control unit on the robotic mower that directs a traction drive system to drive the robotic mower along a path offset a specified distance from an outer boundary wire loop toward the charging station. The vehicle control unit changes the specified distance randomly or incrementally so that the robotic mower does not take the same path to the charging station each time.
