Foot end trajectory with small oscillation generation method of the adjustable stiffness active flexible joint robot

Abstract

In the foot trajectory planning of quadruped robot with active variable stiffness of flexible joint, the existence of the flexible joints makes quadruped robot legs oscillate in swing phase. In this case, this paper proposes a joint stiffness coefficient adjustment strategy and a new foot trajectory generation method. Simulation experiments show that this method can effectively reduce the volatility of legs in swing phase.
