Abstract : The paper presents an analysis of the motion of the legs and the center of gravity of the torso in walking. The analysis is based on the hypothesis that the behavior will be such as to minimize the amount of muscle effort and be consistent with constraints imposed by muscle behavior and geometry. The equations of motion are solved by a shooting technique which is made to satisfy conditions imposed at the beginning and end of a step cycle by an interval halving method. Results give the time phased position of the legs and the torso center of gravity and the moment inputs at the pelvis and the knee. Comparisons of results are made with available experiments and analysis. Results and comparisons are displayed in graphical form. (Author)
