Isaac Asimov's Robot City - Robot City

Robot City

The Robot City novels begin revolving around a man who has no memory of who he was, but believes he might be called Derec after a name-badge he is wearing. Derec journeys to Robot City, a city of robots, with a handful of transient humans. There, Derec meets another mysterious person calling herself Katherine, whose real name turns out to be Ariel, and together the two disprove their role in the apparent murder of a human whose identity is not known by the robots. Fleeing an increasingly dangerous Robot City, Derec and Ariel journey to Earth to find the city's creator, the insane Dr. Avery and learn their true identities. As the series goes on, Both Ariel and Derec are repeatedly asked to confront more questions as old ones are answered, all of which, no matter how broad, always seem to connect with Robot City.

The series makes much use of the Three Laws of Robotics and their interpretations and interactions when dealing with obscure scenarios, such as levels or priority in conflicting orders, a human brain in a robot body, and do the laws apply to non-human, but sentient beings. It also addresses, in passing, differences in interpretation of the First Law, namely, the difference between physical harm and psychological harm.
