The document provides a history of robots from ancient Greek machines in 270 BC to modern applications. It notes that the first robots were devices like water clocks built by Greek engineers. The term "robot" was coined in 1921 in a play, and Isaac Asimov popularized robots in fiction in the 1940s and established the Three Laws of Robotics. Modern robots are used widely in manufacturing, the military, space exploration, medicine, and personal applications. While robots provide benefits, concerns exist about job loss and potentially hostile robots.
