I want to know if The Three Laws of Robotics are explicitly defined in one of the Asimov's robot stories. In which one? I am asking this question because I remember reading something about the laws being compiled by his editor.
The Three Laws are listed in full in many of his robot stories. This was particularly important in some of the Donovan and Powell stories in I, Robot since they were playing around with things that might go wrong.
Asimov's laws are stated in MANY of his short stories, as well as the Elijah Bailey novels. In fact, many of the short stories that had the laws as integral to the plot had the laws STATED at the very beginning, verbatim ("Little Lost Robot" comes to mind).
