Robot (Cyberiad)

Robots are sentient machines living across the Universe in the sci-fi books Cyberiad and Fables for Robots written by Polish writer Stanisław Lem.

Origin and history
Robots evolved from so called Iron Angels, first machines able to make ethical decisions. Iron Angels were created by Humans to do the hardest and the most dangerous works. The Forefather of Robot kind was Calculator Genetoforius, who invented the algorithm of electroincarnation and so he made the first sapient Robots able to reproduce.
