Abstract: A position controller for a quadruped robot with high payload was proposed. The robot was developed by the lab, and the high payload capacity was realized by the specific design of its actuation system, integrating novel high precision actuators, and by its legs, composed by a new family of parallel mechanisms. The foot trajectory was scheduled based on the Bezier curve in order to improve the stability of quadruped robot. The performance and efficiency of the proposed methods were verified by simulation and experiments.

Key words: quadruped robot, gait planning, even terrain, trajectory planning
