... of the very motion of a hopping leg. It consists of a spring-loaded inverted pendulum (SLIP) that swings during the phase of contact with the ground (support phase) and is then ejected upwards into the aerial phase (flight phase). The exceptional accuracy of that model is based on the validity...
