Isaac Asimov was a science fiction writer, in the 1940s and 1950s, who came up with the following laws for robots.

First Law

A robot may not injure a human being or, through inaction, allow a human being to come to harm.

Second Law

A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.

Third Law

A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

Forth Law

A robot may not harm humanity, or, by inaction, allow humanity to come to harm. This law precedes all others.
