针对欠驱动机械手多模式抓取问题,提出了一种手指可拆卸、具有复合抓取功能的欠驱动机械手。为了研究欠驱动手的抓取性能,分别研制了一种弹簧自适应3指节手指机构和一种双四连杆3指节手指机构,两种手指机构均使用四连杆机构的运动原理。手指的性质对欠驱动机械手的抓取稳定性影响很大,对欠驱动机械手单个手指的属性进行分析,分析了关节接触点位置及接触力对抓取稳定性的影响,提出了接触力及力矩平衡的研究分析方法,探讨了影响抓取稳定性的因素。
Aiming at the multi-mode grasping problem of the under-actuated manipulator, an under-actuated manipulator with detachable fingers and composite grasping function is proposed. In order to study the grasping performance of the under-actuated manipulator, a spring-adaptive three-knuckle finger mechanism and a double four-link three-knuckle finger mechanism are developed respectively. Both finger mechanisms use the motion principle of four-link mechanism. The nature of the finger greatly affects the grasp stability of the under-actuated manipulator. The properties of a single finger of an under-actuated manipulator are analyzed, and the influence of the position of the joint contact point and the contact force on the grasp stability is analyzed. A theoretical analysis method of the contact force and moment balance is proposed, and the factors affecting the grasping stability factor are discussed.
