There are two major parts of this thesis. First: Establish running motion tra jectories of biped robot joints. Second: Improve controller of biped robot sys tem. The model of biped robot used in this thesis has 17 bodies with 16 joints and 42 degrees of freedom. On the study of running motion planning, running m otion stable rules is established to create trajectory in accordance with dyna mic characteristics and requirement of stability of running. This method is mo re efficient than geometric operation with efctive vector approach. For the co ntrol of system, existing controller [1] is modified to improve scheduled acce leration error. New controller is more flexible and can be applied to differen t motion trajectory tracking (example: walking, standing, running......) and i mprove the motion speed of the biped robot.
