 Instead of opening credits, the beginning of the movie features Asimovs 3  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 orders given it by human beings except where such  orders would conflict with the First Law.  3. A robot must protect its own existence as long as such protection does  not conflict with the First or Second Law.
