In human hopping in place, the axial leg function is representable by a spring mass model. This description can be utilized to control robot hopping. In this paper, the SLIP (spring loaded inverted pendulum) model is employed as a template for the control of MARCO Hopper II, a robot with a two-segmented leg. Using VMC (virtual model control) a spring is emulated between the foot and hip joint. The required knee torque is generated by a cable-driven actuator to mimic the unilateral knee extensor… CONTINUE READING
