The Three Laws of Robotics lyrics
by Isaac Asimov
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 Law.
0. A robot may not harm humanity, or, by inaction, allow humanity to come to harm.
