Abstract

A new type of three translational parallel robot mechanism was put forward,mechanical principle and freedom of the mechanism which can realize three dimensional translation were analyzed by screw theory,the position of driving pair of the mechanism was judged.The forward and the inverse solutions of the mechanism were analyzed,the velocity and acceleration analysis was carried out,and the kinematics decouplity of the input-output component of the mechanism was discussed.
