First Law: A robot may not injure a human being or, through inaction, allow a human being to come to harm. Second Law: a robot must obey orders given it by human beings except where such orders would conflict with the First Law. Third Law: A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. Given these three laws, etched into every robot's positronic brain, robots must live alongside humans. They can astonish - and perhaps surpass - their creators. Here, Isaac Asimov, one of the Grand Masters of science fiction, tells us the stories of the robots of which he dreamed, from the first days of their creation to the days of their ultimate sophistication.
