[0002] With socio-economic development, the demand for pool cleaning is increasing, requiring pool cleaning robots to clean up debris in complex underwater environments. Since pool bottoms may have slopes and bumps, four-wheeled robots are prone to slipping, while tracked locomotion can reduce this. Current tracked solutions typically engage tracks with the front and rear wheels, with a drive motor driving one wheel, which in turn drives the other wheel via the track. However, in this design, the track serves both as a locomotion and transmission mechanism, requiring a certain preload, increasing the motor load, and the track is prone to aging and breakage under prolonged preload tension.
