Isaac Asimov's Three Laws of Robotics
A robot may not injure a human being or, through inaction, allow a human being to come to harm.
A robot must obey any orders given to it by human beings, except where such orders would conflict with the First Law.
A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
The “Zeroth” Law:
A robot may not harm humanity, or, by inaction, allow humanity to come to harm.
