Asimov's Laws of Robotics

The 3 laws of robotics as Asimov wrote them:

  1. First Law
    A robot may not injure a human being, or, through inaction, allow a human being to come to harm.
  2. Second Law
    A robot must obey orders given it by human beings, except where such orders would conflict with the First Law.
  3. Third Law
    A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
