手是人体最灵巧部分及与外界交互重要媒介，其运动功能康复重建或补充增强是改善障碍患者生活质量、免除身心受害、回归社会必由之路。新兴可穿戴机器人外肢体能创新人类肢体固有形态，突破传统局限，在增强手部运动功能与大脑神经重塑方面有突出新潜能。然而，至今对外肢体应用潜力认识尚处表浅、缺乏客观量化科学描述，机械构型和运动尚不拟人，严重影响外肢体可实现运动能力补充和增强效果。本项目拟以双手协作运动为研究切入点，通过行为学实验探索双手协作静态抓取容差能力和灵巧操作能力，客观量化阐述外肢体可实现手部运动能力的增强效果，优化双手协作构型，解析其运动规律，开拓双手协作运动机械复现和协同控制新方法，创新设计独具双手运动功能的单手仿人外肢体，探索其神经重塑机制，为赋予人手更稳、更广抓取和更灵巧操作性能提供最新科学依据。项目预期成果有望为手功能障碍患者理想康复带来新希望，还在外科临床、军事科学等领域具有广阔应用前景。

Hand is the most dexterous part of the human body and an important medium for interaction with the environment. The rehabilitation and enhancement of hand movement functionality is the only way for disabled patients to improve the quality of life, avoid physical and mental damage, and return to society. Emerging wearable supernumerary robots can innovate human limb morphology, break through the traditional limitations, and perform prominent potentials in enhancing hand movement and brain neural plasticity. However, the understanding of the potential application is still superficial until now, it is lack of the objective and quantitative scientific description, and the anthropomorphism of mechanical configuration and movement are highly limited, which seriously affect the movement ability supplement and enhancement effect of supernumerary robot. This project intends to take the human bimanual movement as the starting point, explore human tolerance grasp and manipulation ability of human bimanual cooperation through the behavioral experiment, objectively quantify the enhancement effect of supernumerary robot to the hand movement functionality, optimize the bimanual cooperative configuration, analyze the movement characteristics, develop the novel mechanical implementation and synergistic control methods, innovatively design the anthropomorphic supernumerary robot worn with bimanual movement functionality, and explore its neural plasticity, which will provide the latest scientific evidence for the enhancement of human grasp stability, tolerance range and manipulation dexterity. The achievements of this project are expected to raise new hopes for hand dysfunction patients with an ideal rehabilitation, and also can be applied to a wide field such as clinical surgery and military science.
