Flexible variable stiffness actuator is divided into four categories including elastic element, pneumatic element, electric-magnetic element and intelligent material. It is gradually applied in rehabilitation robot. It could adapt the change of patient's impedance in the upper and lower limb rehabilitation robots, ensure the safety of the wearer in the exoskeleton, and improve the biomimetics in the prosthesis. Variable stiffness driving mechanism for rehabilitation robot still has some disadvantages. It is proposed to have compact structure, low power consumption, good stiffness characteristics, high response rate and progressive output torque curve, etc.
