Three Laws of Robotics that are traditionally put into words—or once were, long ago. They are these: “ ‘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 or Second Law.’
