A 4-DOF wire drive parallel rehabilitative robot with six wires is designed to coordinate and control a patient pelvic movement during the course of rehabilitative training.The statics model and dynamics model of the parallel robot are established and the workspace of this robot is analyzed.Based on the law of human pelvic movement
the trajectory of the wire-driven parallel robot is planned.The changes of the wire length
velocity and acceleration are calculated based on the model.Furthermore
the correctness of the establishment parallel platform kinematics model is verified by experiment.
