The Spring Loaded Inverted Pendulum (SLIP) describes the dynamic walking of humans and animals in a simplified manner. However, realizing such movements by means of a combination of typical articulated legs and linear actuators has some limitations. This paper proposes a leg mechanism that accurately reflects the SLIP based on its mechanical …

The sliders 3 and horizontal hydraulic cylinders 4 on walking-mechanism support shoes 5 [] enable steps to be taken in such a way that leading edge 6 of foot 2 is only slightly raised to a maximum height of 0.1 m. The throttle valve in the hydraulic system for the walking mechanism is the actual component that serves to smooth the descent of foot 2 to the ground.
