4-UPU parallel mechanism can realize 3T1R motion, the mechanism's four motion branched structure configuration is the same, so it is also known as a perfectly symmetrical parallel mechanism.The sym-metric structure can carry on the kinematics and dynamics analysis of the research easily.A concise agency mod-el was established and the structure diagram was drawn.Then, its kinematics was analyzed, and the positive and negative solutions of the algorithm were solved.Finally, a numerical example was given to verify the correctness and rationality of the algorithm.
