摘要：
A robotic mower stuck detection system includes a boundary sensor on the robotic mower that can detect when the robotic mower reaches a boundary wire, an accelerometer on the robotic mower that can detect when the robotic mower encounters an obstacle； and a vehicle control unit on the robotic mower having a timer that is reset each time the robotic mower reaches a boundary wire or encounters an obstacle； and executes a stuck vehicle task if the timer exceeds a specified maximum time without being reset.
