Modelling and Simulation of Human-like Movements for Humanoid Robots

The humanoid robots are bio-inspired models of human body. The mechanical structure of humanoid robots consists of several joints and segments. Numerous degrees of freedom are caused the redundancy problem. There is an unanswered question concerning with strategies which central nervous system implements to predict the human posture and gesture during different movements. A 7 degree of freedom model is used for modelling humanoid robot and an optimization-based method is planned to simulation of human motion. The joints angles and torques are subjected as optimization variables. The joints range of motion and limits of actuator torques are used as optimization constraints. The weight lifting is the motion which is subjected to simulation. Finally the results presented for two velocity lifting. The result shows the body posture varies naturally and the weight maintain at the end position at final time correctly.
