These laws govern the robots' behavior and the use of robots.
A robot may not harm a human or through inaction allow harm to come to a human.
The first law is the law that is impressed into the positronic brain the firmest, and overrides both of the other laws.
A robot must obey 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.
