Design and Kinematics of a Lower Limb Rehabilitation Robot

This paper presents a rehabilitation robot used for the patient with paralysis of lower limb and the kinematics of the mechanism is analyzed. The mechanical design of the robot is described. The forward and inverse kinematics solution of the robot is given. The working space of the foot apex is calculated under the training range. The trajectory planning is studied. It provides important data reference for the rehabilitation of paraplegia patients.
