Abstract
A robotic mower area coverage system includes a load sensor on the robotic mower signaling load on a cutting blade motor, a boundary sensor on the robotic mower indicating the distance from the sensor to a boundary wire, a timer on the robotic mower indicating when the robotic mower last used a specified boundary coverage, and a vehicle control unit on the robotic mower selecting the type of area coverage based on input from the load sensor, the boundary sensor and the timer, and commanding a pair of traction drive motors to drive the robotic mower using the selected type of area coverage.
