Provided is a wheel-leg composite type four-leg robot. The wheel-leg composite four-leg robot is characterized by comprising an inner car frame, an outer car frame, a cushioning assembly, two pairs of upper leg parallel connection assemblies and four wheel type legs with identical structures. The inner car frame is arranged inside the outer car frame. The inner car frame is connected with the outer car frame through the cushioning assembly. The upper leg parallel connection assemblies of two front legs arranged below the outer car frame are symmetric with each other in a left and right mode, and two front-wheels type legs connected with the parallel connection assemblies are symmetric in a left and right mode. The upper leg parallel connection assemblies of two rear legs arranged below the inner car frame are symmetric with each other in a left and right mode, and two rear-wheels type legs connected with the parallel connection assemblies are symmetric with each other in a left and right mode. Each leg is in a (2-UPS+U) R series and parallel hybrid connection. The wheel-leg composite type four-leg robot has the advantages that the load is big, the rigidity is good, the coupling is small, the obstacle crossing advantage of the leg mechanism is fully applied, the complexity of the control and a mechanical structure is lowered, the installation is easy and convenient, and the maintenance is convenient. The positions and stress information of upper legs and lower legs can be obtained through sensors, and the self-adaption control in an unknown environment can be achieved.
