[quote]The robot laws A robot may not injure a human being or, through inaction, allow a human being to come to harm. A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. A robot cannot, through action or inaction, harm humanity. Precedes all other laws.[/quote] I wonder if this a reference from the movie i robot.
