By Isaac Asimov (1920 – 1992)
The three fundamental Rules of Robotics…One: a robot may not injure a human being, or, through inaction, allow a human being to come to harm…Two:..a robot must obey the orders given it by human beings except where such orders would conflict with the First Law… Three: a robot must protect its own existence as long as such protection does not conflict with the First and Second Laws.
