THREE LAWS OF ROBOTICS

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