Abstract
A robotic lawn mower includes a mowing element, a body, a drive assembly, a first detection module, a second detection module, a failure determination module, an execution module, and a control module. The first detection module detects a first journey of the robotic lawn mower in a period. The second detection module detects a motion parameter of the drive assembly in the period and calculates a second journey of the robotic lawn mower in the period. The failure determination module determines whether a difference between the second journey and the first journey is greater than or equal to a first preset value. The execution module drives the robotic lawn mower to execute a response program. When the difference is greater than or equal to the first preset value in each of n1 consecutive periods, the control module controls the execution module to execute the response program.
