For example, the control unit may receive the rotation speed signals of the first and second rotation speed sensors, convert the rotation speed signals into rotation speed values, and may accurately compare the rotation speed differences in real time, and, when the rotation speed difference value is greater than a rotation speed difference preset value preset in the control unit, disconnect the clutch on the high speed side (e.g., disconnect the first clutch between the first drive shaft 9 and the first drive shaft 6 to stop transmitting the drive force when the rotation speed of the first wheel is high) to stop the transmission of the drive force, so that the high speed side becomes driven, at which time the wheel rotation speed may decrease on the high speed side under the resistance, and reconnect the previously disconnected clutch (e.g., reconnect the first clutch between the first drive shaft 9 and the first drive shaft 6 to transmit the drive force) when the rotation speed difference value on both sides decreases and is less than the rotation speed difference preset value.

In addition, the single motor directly drives the first walking unit 1 and the second walking unit 2, compared with the driving of a single motor gear rack or the driving of wheels by two motors on two sides in other schemes, because a clutch structure is adopted, when the movable beam body 3 is switched in place and locked, the freedom degree of the movable beam body 3 can be released by disconnecting the clutch, the problem of serious structural abrasion caused by extrusion of the gear rack or sliding friction between the wheels and the track 14 when the position of the movable beam body 3 is locked and corrected due to switching precision and the like after the motor is braked is avoided, and the service life is prolonged.
