机器人按ISO 8373定义为:位置可以固定或移动,能够实现自动控制、可重复编程、多功能多用处、末端操作器的位置要在3个或3个以上自由度内可编程的工业自动化设备。这里自由度就是指可运动或转动的轴。工业机器人按其结构形式及编程坐标系主要分类为关节型机器人、移动机器人、水下机器人和直角坐标机器人等。按主要功能特征及应用分类为移动机器人、水下机器人、洁净机器人、直角坐标机器人、焊接机器人、手术机器人和军用机器人等。 According to ISO 8373, robots are defined as: industrial robots that can be fixed or moved in position, automatic control, reprogrammable, versatile and versatile, with terminal operator position programmable in 3 or more degrees of freedom. Freedom here refers to the axis of movement or rotation. Industrial robots according to their structure and programming coordinate system is mainly classified as joint-type robots, mobile robots, underwater robots and Cartesian robots and so on. According to the main functional characteristics and applications classified as mobile robots, underwater robots, clean robots, Cartesian robots, welding robots, surgical robots and military robots.
