Document Type and Number:
WIPO Patent Application WO/2021/254462
Kind Code:
A1
Abstract:
A grass mowing robot (100), comprising a grass mowing element (11), a machine body (12), a driving assembly (15), a travel wheel (131), a motor (14), a first detection module (161), a second detection module (162), a fault determination module (17), an execution module (19) and a control module (182). The first detection module (161) detects a first travel distance of the grass mowing robot (100) within a cycle; the second detection module (162) detects a movement parameter of the driving assembly (15) within the cycle and calculates a second travel distance of the grass mowing robot (100) within the cycle; the fault determination module (17) determines whether the difference between the second travel distance and the first travel distance is greater than or equal to a first preset value; the execution module (19) drives the grass mowing robot (100) to execute a response program; and the control module (182) is respectively connected to the fault determination module (17) and the execution module (19), wherein when the difference between the second travel distance and the first travel distance is greater than or equal to the first preset value within each cycle of n1 consecutive cycles, the control module (182) controls the execution module (19) to execute the response program.
