The snakelike robot composed of nine joints was proposed in this paper.The serpentinelocomotion multibody mechanism of snakelike robot was studied,and its moving model was established in thesystem dynamics simulation software Recurdyn.The joint angle functionsmotion were set up.By adding some restrictions for model in Recurdyn and setting of serpentine locomoving functions,the simulation was introduced the input of the joint angle function’s influence on the winding movement of the snakelike robot.The simulation results show that the snakelike robot can completethe serpentine locomotion set before.
