Abstract: This paper researches the motion planning of under-actuated bionic robot which named Rock & Roll Robot-RRRobot. According to the dynamic model of RRRobot, the objective is minimizing the energy loss; the improved Particle Swarm Optimization（PSO） algorithm based on genetic operator is proposed. At last, it gets motion planning of the robot from an initial state to a target state, and optimizes the motion planning on RRRobot. The simulation results show the improved PSO algorithm, compared with the PSO algorithm, the terminal configuration of the RRRobot error and system power consumption has significantly improvement.
