Abstract：
 The invention relates to a bionic ankle joint. The ankle joint uses joint bearing. The bearing inner ring is connected with the calf and the outer ring is connected with the foot. The outer ring revolves the inner ring. The foot of the robot is driven to move relative to the calf. The uplifting and unbending motion of ankle joint and the rotary motion along the axis line of the calf are respectively controlled by a pair of springs. One end of the spring is connected with the calf and the other end is connected with the foot. When the robot dumps towards the sideways, the equilibrium position is recovered under the function of spring. The invention can realize flexible motion of ankle joint with homocentric triaxiality with compact structure. The energy loss can be reduced using the mode of combining the pneumatic muscle active control and spring passive control and the effect of buffering can be obtained.
