Issac Asimov's Three Laws of Robotics
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, exept where such orders would conflict with the First Law.
3. A robot must protect it's own existance, except where such protection would conflict with the First or Secon Law
