Laws of Robotics

Isaac Asimov first postulated his three “Laws of Robotics” in 1940. The were designed to protect humans,
so that no robot could harm a person.

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 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 Laws.

In 1985 he detected the need for the first law to be extended which protected individual human beings,
so it would protect humanity as a whole. He added the zeroth law, which states:

0: A robot may not injure humanity, or, through inaction, allow humanity to come to harm.
