旋转坐标型手臂能提供了较大的灵活性,而且只需要很少的部件。本期中所讨论的手臂只有两个自由度。但是,你会发现,虽然只有两个自由度,该手臂也能做许多事情。它可作为静止的“拿起一放下(物体)”型的机器人单独使用,也可以装在移动的平台上。本期给出的构建手臂的讨论只针对左手臂,右手臂的构建只是左手臂的镜像。你会注意到手臂上缺少手掌—抓取器。但是,它可以连接任意类型的抓取器。事实上,你可以自行设计其前臂使其可接受能替换的不同类型的抓取器。手部的抓取装置的设计方案将在以 Rotary coordinates arm provides great flexibility, but requires very few parts. The arms discussed in this issue have only two degrees of freedom. However, you will find that the arm can do many things, though with only two degrees of freedom. It can be used as a stand-alone “pick up a drop (object)” type of robot alone, can also be mounted on the mobile platform. The discussion of building arms given in this issue is for the left arm only, and the building of the right arm is just a mirror image of the left arm. You notice the lack of palms on the arms - the gripper. However, it can connect to any type of grabber. In fact, you can design your own forearm to accept different types of graspers that can be replaced. Hand gripping device design will be in
