Quadruped bio-robot

The invention discloses a quadruped bio-robot comprising a control system and a mechanical system. The mechanical system comprises two trunks and a waist adjusting motor arranged between the two trunks for adjusting swinging of the trunks. Each trunk is connected with two leg mechanisms, each leg mechanism comprises a multi-degree-of-freedom hybrid mechanism and a driving motor driving the hybrid mechanism to swing, the swing axis of the hybrid mechanism is parallel to that of the two trunks, and the control system coordinates and controls the waist adjusting motor and the driving motors to achieve continuous swing of the two trunks and the four leg mechanisms as well as realize jumping. Through the waist adjusting motor and the four leg mechanism, the control system coordinates and controls the waist adjusting motor and the driving motors to drive the two trunks and the four leg mechanism to swing, so as to realize attitude changes of the overall mechanism, and further continuous jumping actions are realized
