Analyzing Effects of Ankle-Foot Parameters on Passive Bipeds Based on Dynamic Walking Modeling
Though people’s usual gaits tend to be natural and simple, the theoretical modeling and analysis are complicated based on the remarkable fact that the walking motion is a complex dynamic phenomenon. In this paper, we build a passive dynamic bipedal walking model with flat feet and compliant ankle joints. The bipedal walker travels on a slope actuated by the gravity. We analyze effects of ankle-foot parameters on walking characteristics based on dynamic walking modeling. Simulation results demonstrate that the model can perform stable walking cycle. The effects of ankle-foot parameters on motion characteristics with different ankle stiffness are shown in detail.
