Trajectory Generation Method of Biped Robot for All Direction Walking on the Sloping Surface

In this paper, the trajectory generation method to make the biped robot walk in every direction on the sloping surface is proposed. In order to simplify the biped robot, the robot is assumed to be one particle, and reference coordinate is established to generate stable trajectory of biped robot on the sloping surface and towards direction of locomotion appropriately. The moment equation based on reference coordinate is set up and is used to generate trajectory of sagittal plane and lateral plane. Since this trajectory generation method considers direction of robot locomotion and angle of inclination, it makes the biped robot walk on the sloping surface stably. Biped robot can walk on the sloping surface by using proposed method without any control algorithm. The effectiveness of proposed method was proved by using computer simulation
