ASIMO, a humanoid robot.

In science fiction, the Three Laws of Robotics are a set of three rules written by Isaac Asimov, which most robots appearing in his fiction must obey. Introduced in his 1942 short story "Runaround", the Laws 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.

According to the Oxford English Dictionary, the first passage in Asimov's short story "Liar!" (1941) that mentions the First Law is the earliest recorded use of the word robotics. Asimov was not initially aware of this; he assumed the word already existed by analogy with mechanics, hydraulics, and other similar terms denoting branches of applied knowledge.

The Three Laws form 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 Laws may have in the future.
