This document discusses robotics and robotic history. It defines a robot as a re-programmable machine that can perform tasks in place of humans. The word "robot" was introduced in a 1920 play and the term "robotics" was coined in the 1940s. The first digital and programmable robot was invented by George Devol in 1954. The document outlines the typical components of industrial robots and describes common types of robots including mobile, stationary, autonomous, and virtual robots. It discusses potential applications and limitations of robotics. In the future, robots may be used to explore space, perform dangerous tasks, and work continuously.
