The Caves of Steel, the first of Asimov's classic robot novels, and the celebrated stories included in his timeless collection The Rest of the Robots, offers an intriguing insight into robot thought processes. All robots must follow the three laws, but that leaves room for a surprisingly wide range of unexpected outcomes... THE THREE 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 the orders given to 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 Laws.
