Kinematic Modeling and Simulation of Eleven-Links Biped Robot With Arms

Abstract

Gait generation for humanoids and humanoid walking has been subject of many researches in robotics. This paper focuses on mathematical simulation of biped robots and investigating walking stability regarding zero moment point (ZMP) criteria; it also proposes a simple algorithm for humanoid walking with more links such as arms and forearms using proper parameters. Raising the number of links, the number of effective parameter instability grows rapidly and leads to be complicated and time consuming equations. In order to tackle the issue, a new method, step by step ZMP calculating is used. It can be seen that robot walking pattern with the swinging arm and forearm is like a human walking patterns. Besides, it is understood that a robot with arms has more stability in comparison with the robot without arms. Moreover, it is concluded that robot with forearms has more stability in comparison with the robot with arms.
