  • 基于人体手部运动协同性,用连杆机构简化驱动结构。
  • 11个电机控制19个关节,重520克,成本约400美元。
  • 适合需要高灵巧性的机器人应用,如抓取与精细操作。

设计兼具功能灵巧性与机械简洁性的类人机器人手仍是重大挑战。受人体手部协同机制启发,本文提出SyLink手,将生物力学协同原理与连杆传动机制结合,在紧凑且低成本的架构中实现外观、运动学和功能的高度类人化。通过动作捕捉手套对自然手部运动的生物力学分析,揭示了关节间强烈的运动相关性,为简化但功能完整的自由度(DOF)配置提供依据。基于这些协同特性,优化的连杆机构协调多个关节运动,重现自然指节轨迹。进一步提出一种新型球面四杆连杆机构,在紧凑结构中实现掌指关节处屈伸与内收外展的解耦。原型机集成19个关节,由11个执行器驱动,总质量520克,制造成本约400美元。实验评估表明其具备类人运动性能、高承载能力及多样的抓握与操作技能。结果验证了该协同启发、连杆驱动的设计能有效平衡类人化、机械简洁性与功能多样性,展现出在高灵巧性机器人应用中的实际部署潜力。

原文摘要 · Abstract (English)

Designing anthropomorphic robotic hands that balance functional dexterity with mechanical simplicity remains a significant challenge. Inspired by human hand synergies, this paper presents the SyLink Hand, an anthropomorphic dexterous hand that integrates biomechanical synergy principles with linkage-driven transmission mechanisms to achieve a high degree of anthropomorphism in appearance, kinematics, and functionality within a compact and cost-effective architecture. Biomechanical analysis of natural hand motions using motion capture gloves reveals strong kinematic correlations among hand joints, providing the basis for a simplified yet functional degree-of-freedom (DOF) configuration. Guided by these synergistic characteristics, optimized linkage mechanisms are employed to coordinate multiple joint motions and reproduce natural finger trajectories. A novel spherical four-bar linkage is further proposed to achieve decoupled flexion/extension (Flex/Ext) and abduction/adduction (Abd/Add) at the metacarpophalangeal joint within a compact form factor. The resulting prototype integrates 19 joints driven by 11 actuators, with a total mass of 520g and a manufacturing cost of approximately USD 400. Experimental evaluations demonstrate its human-like kinematic performance, high load-bearing capability, and versatile grasping and manipulation skills. These results validate that the synergy-inspired, linkage-based design effectively balances anthropomorphism, mechanical simplicity, and functional versatility, highlighting its potential for practical deployment in dexterity-demanding robotic applications.
