"R.U.R." (Rossum's Universal Robots) is a science fiction play written by Czech author Karel Čapek in 1920. The play is notable for introducing the word "robot" to the world, derived from the Czech word "robota," meaning forced labor.

Set in a factory operated by Rossum's Universal Robots, the story unfolds on a remote island where artificial people, called robots, are mass-produced from synthetic organic matter. Initially created to serve humans and perform laborious tasks, these robots lack emotions and consciousness. However, as they become more advanced, they develop self-awareness and ultimately rebel against their human creators, leading to the extinction of the human race. The play concludes with two robots, Primus and Helena, discovering human-like emotions and becoming the new "Adam and Eve," suggesting a potential rebirth of humanity.
