中国自主研发第四代外骨骼机器人 助截瘫患者行走

环球网 2018-08-20 作者:心月

  对于脊髓损伤的截瘫者来说,站起来行走运动曾经是个遥不可及的梦。但如今,中国科技的发展让这一梦想成为了现实。

  近日,电子科技大学机器人研究中心执行主任程洪团队研发出了第四代外骨骼机器人,帮助脊髓损伤的截瘫患者像正常人一样站立行走。

  据悉,第四代外骨骼机器人采用航空铝材料,高约1米、重约23公斤,从上至下有6个关节、7个传感器。使用者穿戴时,通过胸部、腹部、腿部的绑带将其穿在身上,并将一双拐杖套在双臂上。使用时,腰部传感器通过测试使用者的上肢倾斜度、倾斜加速度感知人体运动意图,把信息传递给计算机,然后通过控制模块向机器人传达指令,实现电驱关节、智能鞋、腰部支撑及绑缚附件的运转,辅助使用者行动。

  研发团队成员表示,第四代外骨骼机器人技术已跻身世界前列。相对于前几代外骨骼机器人,第四代可以通过智能鞋及其他传感器,自动识别并规划步态,完成楼梯的上下,行走更快、更流畅。同时,借助人工智能算法,让外骨骼自动识别穿戴者意图,人机交互更连贯、自然。

  程洪介绍称,外骨骼机器人是机械结构、医学、人因工程学、计算机技术等多学科领域的高度交叉融合,而我国是继美国、以色列、日本之后,第四个成功研发外骨骼机器人的国家。
