工业机器人如何用六点法定义工具坐标系?
请给出大概的算法！谢谢
推荐回答（3个）
在示教器找到菜单键找到设置 在设置里找到坐标系这一选项 选择工具坐标 选择完成后 选择要示教的标签 按ENTER进入坐标设置试教 完成三个接近点试教后 在SELECT里设一个hom点作为坐标原点记录完成后对X Y轴方向点进行试教 全部试教完毕后应用自己新教的坐标（工具坐标）
三点法和上述相同 但没有原点示教和方向点示教（工具坐标）
常用的机器人编程语言
一、VAL语言及特点
VAL语言是美国Unimation公司于1979年推出的一种机器人编程语言，主要配置在PUMA和UNIMATION等型机器人上，是一种专用的动作类描述语言。VAL语言是在BASIC语言的基础上发展起来的，所以与BASIC语言的结构很相似。在VAL的基础上Unimation公司推出了VALⅡ语言。
VAL语言可应用于上下两级计算机控制的机器人系统。上位机为LSI-11/23，编程在上位机中进行，上位机进行系统的管理；下位机为6503微处理器，主要控制各关节的实时运动。编程时可以VAL语言和6503汇编语言混合编程。

机器人学是一门高度交叉的前沿学科，机器人技术是集力学、机械学、生物学、人类学、计算机科学与工程、控制论与控制工程学、电子工程学、人工智能、社会学等多学科知识之大成，是一项综合性很强的新技术。通过该课程的学习，使得学生基本熟悉这门技术以及其发展状况，为今后从事光机电一体化与系统设计、制造的研究工作打下基础。
Robotics is a new interdiscipline, Robot techniques include mechanics, mechanics, biology, anthropology, computer science, project, cybernetics and controlling engineering, electronic engineering, artificial intelligence, sociology,etc., It is a comprehensive technology. Through studying this course, the students can be familiar with this technology and the development state, and make the foundation in optical, mechanical and electronic integration and research work including system design and manufacture in the future.
