Just follow Asimov's laws of robotics: 0) A robot may not harm humanity, or, by inaction, allow humanity to come to harm. 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 Law.
