Kinematic Analysis of 6-DOF Parallel Robot with Multi-loop Coupling

A multi-loop coupled 6-DOF parallel robot with 3-RSS-PRSS branch type is designed. The kinematics model of the robot is established by vector method, and the kinematics equation is solved. The robot designed not only has the high-speed movement characteristic of DELTA robot, but also has the flexibility characteristic of 6-DOF series robot. The research method of its kinematics position relationship provides reference for kinematics analysis of the same type of robot.
