In one of his early science-fiction stories, the prolific writer Isaac Asimov first mentioned the word “robotics,” along with three fundamental rules that all robots had to obey. The rules, now called Asimov’s three laws, are as follows.
• A robot must not injure, or allow the injury of, any human being.
• A robot must obey all orders from humans, except orders that would contradict the First Law.
• A robot must protect itself, except when to do so would contradict the First Law or the Second Law.
