说明：  机械手臂的设计是目前机器人科学研究的一个热点。这里考虑手臂的抓重、材料和运动 速度，对其进行优化设计。建立了优化设计的数学模型，使用 J)KL)M 软件分析目标函数的性态并 计变量的可行域，求得机械手臂最优尺寸。在满足条件的情况下，使手臂质量最小，证明了该设计
(Mechanical robot arm is designed to present a hot topic of scientific research. Considered here grasping the arm weight, materials and movement speed, to optimize the design. Established a mathematical model of optimal design, using J) KL) M software analysis of the objective function of state and taking into account variables feasible region, and seek the optimal size of mechanical arm. Conditions are met, so that the quality of the smallest arm to prove that the design)
