Dynamic stability of variable stiffness running
— Humans and animals adapt their leg impedance during running for both internal(e.g. loading) and external(e.g. surface) changes. In this paper we examine the relationship betwee...

Feedback linearization and simultaneous stiffness-position control of robots with antagonistic actuated joints
— In this paper, the dynamic model of a robot with antagonistic actuated joints is presented, and the problem of full linearization via static state feedback is analyzed. The use...
