The best known set of laws are those written by Isaac Asimov in the 1940s, or based upon them, but other sets of laws have been proposed by researchers in the decades since then.

Isaac Asimov's "Three Laws of Robotics"

The best known set of laws are Isaac Asimov's "Three Laws of Robotics". These were introduced in his 1942 short story "Runaround", although they were foreshadowed in a few earlier stories. The Three Laws are:

  1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
  2. A robot must obey the orders given 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 Laws.

In "The Evitable Conflict" the machines generalize the First Law to mean:

  1. No machine may harm humanity; or, through inaction, allow humanity to come to harm.

This was refined in the end of Foundation and Earth. A zeroth law was introduced, with the original three suitably rewritten as subordinate to it:

  1. A robot may not injure humanity, or, by inaction, allow humanity to come to harm.

Adaptations and extensions exist based upon this framework. Alan Winfield has said the laws remain a "fictional device".

Additional laws

Authors other than Asimov have often created extra laws.

The 1974 Lyuben Dilov novel, Icarus's Way (a.k.a., The Trip of Icarus) introduced a Fourth Law of robotics: "A robot must establish its identity as a robot in all cases." Dilov gives reasons for the fourth safeguard in this way: "The last Law has put an end to the expensive aberrations of designers to give psychorobots as humanlike a form as possible. And to the resulting misunderstandings...". More formally, in 2024 Dariusz Jemielniak in an article in IEEE Spectrum proposed a Fourth Law of Robotics: "A robot or AI must not deceive a human by impersonating a human being."

A fifth law was introduced by Nikola Kesarovski in his short story "The Fifth Law of Robotics". This fifth law says: "A robot must know it is a robot." The plot revolves around a murder where the forensic investigation discovers that the victim was killed by a hug from a humaniform robot that did not establish for itself that it was a robot. The story was reviewed by Valentin D. Ivanov in SFF review webzine The Portal.

For the 1986 tribute anthology, Foundation's Friends, Harry Harrison wrote a story entitled, "The Fourth Law of Robotics". This Fourth Law states: "A robot must reproduce. As long as such reproduction does not interfere with the First or Second or Third Law."

In 2013 Hutan Ashrafian proposed an additional law that considered the role of artificial intelligence-on-artificial intelligence or the relationship between robots themselves – the so-called AIonAI law. This sixth law states: "All robots endowed with comparable human reason and conscience should act towards one another in a spirit of brotherhood."
