摘要: 目的 针对目前大多数上肢康复机器人串联式结构的弊端,设计一款新型四自由度上肢康复机器人。 方法 将肩、肘关节驱动系统及信息检测系统集中放置在基座内,设计同步带传动系统及弧齿锥齿轮传动系统将动力经过杆件从基座内传递至机械臂的肩、肘关节;选用基于关节空间的三次多项式轨迹规划法对取物和画四边形两种动作进行轨迹规划,并设计单自由度运动控制实验及多自由度轨迹规划实验验证设计的合理性及可行性。 结果 该康复机器人各关节均能按照设计的速度达到设计的运动范围,且能够较准确地完成规划好的康复训练动作。 结论 该机器人有效减小了机械臂的体积和质量,克服了电机噪声、辐射等对患者康复训练的影响,且能够辅助患者完成多种康复运动。

Abstract: Objective A novel four-degree-of-freedom upper limb rehabilitation robot was designed to overcome the shortcomings of the structure of the most of serial robots. Methods The shoulder and elbow joint drive system and the information detection system were placed in the base. The synchronous belt drive system and the spiral bevel gear transmission system were designed to transmit power from the base to the shoulder and elbow joint of the arm. The cubic polynomial trajectory planning method based on the joint space was selected to accomplish the trajectory planning of the recovery movements of taking objects and drawing quadrilaterals, and the single-degree-of-freedom motion control experiment and multi-degree-of-freedom trajectory planning experiment were designed to verify the rationality and feasibility of the design. Results Each joint of the rehabilitation robot reached the designed range of motion at the designed speed, and well completed the planned rehabilitation training movements. Conclusion This robot can effectively reduce the volume and mass of the mechanical arm, overcome the influence of motor noise and radiation on patients' rehabilitation training, and assist patients to complete a variety of rehabilitation exercises.
