Runaround

"Runaround" is a science fiction short story by Isaac Asimov, featuring his recurring characters Powell and Donovan. It was written in October 1941 and first published in the March 1942 issue of Astounding Science Fiction. It appears in the collections I, Robot (1950), The Complete Robot (1982), and Robot Visions (1990).

In common with many of Asimov's Robot stories, the application of the Three Laws of Robotics is the subject, though in contrast to the majority (in which the lexical ambiguities of the Laws are employed to fashion a dilemma), the robot featured in "Runaround" is actually following the Laws as they were intended.

Runaround is notable for featuring the first explicit appearance of the Three Laws of Robotics, which had hitherto only been implied in Asimov's robot stories.
