Transformable wheel-foot movement type robot

The invention discloses a transformable wheel-foot movement type robot. The transformable wheel-foot movement type robot comprises a control system and a mechanical system, the mechanical system comprises a trunk, a wheeled movement mechanism and four multi-degree-freedom-of-movement leg movement mechanisms mounted on the trunk, the wheeled movement mechanism comprises four wheels and a driving motor for driving at least one of the wheels, the four wheels are mounted in the rear of the mechanical system, every leg movement mechanism comprises a plurality of serially connected steering gears with output shafts perpendicular to one another, and the control system controls the steering gears to rotate to adjust positions and postures of the leg movement mechanisms. Through the leg movement mechanisms and the wheeled movement mechanism, the transformable wheel-foot movement type robot moves on the flat ground through the wheeled movement mechanism, and achieves switching between a wheeled movement mode and a foot
