摘要:

柔顺变刚度驱动机构分为弹性元件、气动元件、电-磁元件和智能材料四大类。变刚度驱动机构正在逐步应用于康复机器人,在上下肢康复机器人中可适应患者的阻抗变化,在外骨骼中可保证穿戴者的安全,在假肢中可提高仿生性。现有康复机器人变刚度驱动机构还存在一些问题,还应具备紧凑的结构、低能耗、良好的刚度特性、高响应速率和渐进式输出扭矩曲线等特点。

关键词: 变刚度, 柔顺, 康复机器人, 综述

Abstract:

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.

Key words: variable stiffness, flexiblity, rehabilitation robot, review
