The Three Laws of Robotics are a set of three science fiction laws written by Isaac Asimov, which most robots appearing in his fiction have to obey. First introduced in his short story "Runaround" (1942), they state the following:

1. A robot may not harm a human being, or, through inaction, allow a human being to come to harm.
2. A robot must obey the orders given to it by human beings except where such orders would conflict with the First Law.
3. A robot must protect its own existence, as long as such protection does not conflict with the First or Second Law.

The Three Laws are an organizing principle and unifying theme for Asimov's fiction, appearing in the Foundation series and the other stories linked to it, as well as Lucky Starr and the Moons of Jupiter. Other authors working in Asimov's fictional universe have adopted them, and references (often parodic) appear throughout science fiction and in other genres. Technologists in the field of artificial intelligence, working to create real machines with some of the properties of Asimov's robots, have speculated upon the role the Three Laws play in such research.
