Three Laws for Robots, by Isaac Asimov
Law #1: A robot may not harm a human
being
Law #2: A robot must obey orders given to
it by human beings except where such
orders would conflict with the First Law
Law #3: A robot must protect its own
existence as long as such protection does
not conflict with the First or Second Law
Additional law: A robot must know it is a
robot (should robots have feeling?!)

Definition for Robots from Wikipedia

A robot is a mechanical or virtual,
artificial agent. It is usually an
electromechanical system, which, by its
appearance or movements, conveys a sense
that it has intent or agency of its own.

A certain level/degree of intelligence
