This study aims to optimize the geometrical parameters of an under-actuated mechanical finger by conducting a theoretical analysis of these parameters. The finger is actuated by a flexion tendon and an extension tendon. The considered parameters are the tendon guide positions with respect to the hinges. By applying such an optimization, the correct kinematical and dynamical behavior of the closing cycle of the finger can be obtained. The results of this study are useful for avoiding the snap-through and the single joint hyperflexion, which are the two breakdowns most frequently observed during experimentation on prototypes. Diagrams are established to identify the optimum values for the tendon guides position of a finger with specified dimensions. The findings of this study can serve as guide for future finger design.

This paper aims to present general design considerations and optimality criteria for underactuated mechanisms in finger designs. Design issues related to grasping task of robotic fingers are discussed. Performance characteristics are outlined as referring to several aspects of finger mechanisms. Optimality criteria of the finger performances are formulated after careful analysis. A general design algorithm is summarized and formulated as a suitable multi-objective optimization problem. A numerical case of an underactuated robot finger design for Laboratory of Robotics and Mechatronics (LARM) hand is illustrated with the aim to show the practical feasibility of the proposed concepts and computations.

用HVS-1000显微硬度测试仪、X-350A型X射线应力测定仪,以2.5 kW SM2000SM快轴流CO2激光器对0.6 mm厚的TA2板料进行扫描,按照正交试验理论安排成形工艺参数,研究了TA2板料弯曲成形时主要工艺参数对弯曲角度的影响,以及试样表面残余应力的分布和试样断面上的显微硬度变化。结果表明:正交试验中的4个工艺参数的作用是不同的,按其变化对弯曲变形量影响的大小排序,依次是扫描次数、光斑直径、激光束功率、扫描速度;成形参数对试样表面的残余应力分布也存在一定的影响;试样变形区断面上的显微硬度变化呈现出一定的规律。
