The document discusses different types of robots. It defines a robot as a reprogrammable, multifunctional manipulator designed to move materials and parts through variable programmed motions to perform tasks. The key parts of most robots are sensors, effectors, actuators, controllers, and arms. The document then describes four types of robots: stationary robots that perform repeating tasks without moving; autonomous robots that are self-contained and rely on their own control systems; remote-control robots that can be guided by a person from a distance; and virtual robots that exist as computer programs, not physically. It includes a link to a video showing how robots are used in the automotive industry.
