Abstract

Based on new bipedal running model, a new feedback mechanism which included swing-leg retraction and control force is proposed to maintain stable running. The mechanical characteristics, control mechanism and stability in running are studied. And the dynamic response of bridge under new bipedal running model is also analyzed. The results show that the new bipedal running model can reproduce periodic running cycle. The new feedback mechanism allows the running model to automatically adapt the motion state and compensate for energy dissipated. The stability of running model is significantly improved. And the human-structure dynamic interaction is weak when human run.
