摘要: 脑卒中是一种神经损伤性疾病,是我国成人致死、致残首位病因,给家庭和社会造成巨大负担。机器人技术可有效帮助脑卒中患者进行神经重塑和肢体康复。手腕关节作为人体最为灵活的关节之一,其功能障碍将严重降低患者生活质量。因此,设计了一种基于并联机构的、用于腕关节康复的外骨骼机器人。设计考虑手腕关节骨骼结构,提出一种新的更符合其生物学运动特征的腕关节简化模型。基于该模型利用旋量理论对所设计外骨骼的人机匹配性及运动特性进行分析。建立该外骨骼机构的运动学模型,进行奇异性、工作空间及灵巧度等运动学性能评价,并对其驱动特性进行研究。结果表明设计可满足腕关节康复需求,并可实时匹配运动腕关节中心;与已有研究相比,所设计外骨骼具备良好运动学性能并可实现驱动解耦。

Abstract: Stroke is a neurodegenerative disease, and the leading cause of death and disability among adults in China, which places a significant burden on families and society. Robotic technology can effectively assist stroke patients in neuroplasticity and limb rehabilitation. The wrist joint, as one of the most agile joints in the human body, its dysfunction can significantly degrade the quality of life for patients. Therefore, an exoskeleton robot based on a parallel mechanism has been designed for wrist rehabilitation. The design considered the skeletal structure of the wrist and proposed a novel reduced model that more accurately reflects the biomechanical characteristics of the wrist joint’s movement. Based on the model, the human-machine compatibility and motion characteristics of the designed exoskeleton are analysed by employing the screw theory. The kinematic model of the exoskeleton mechanism is established, and its kinematic performance such as singularity, workspace, and dexterity were evaluated, along with an analysis of its actuation feature. The results indicated that the design meets the rehabilitation needs of the wrist joint and can match the movable wrist joint centre in real-time. Compared to existing studies, the designed exoskeleton exhibits superior kinematic performance and achieves actuation decoupling.
