Risk (Asimov)

Risk is a science fiction short story by Isaac Asimov, first published in the May 1955 issue of Astounding Science Fiction, and reprinted in the collections The Rest of the Robots (1964) and The Complete Robot (1982).The story is a sequel to "Little Lost Robot". It is set in the same location, but involves a different positronic robot - one of the few in Asimov's stories to have neither a serial number nor nickname.The researchers at Hyper Base are ready to test the first hyperspace ship, which has a positronic robot at the controls as it is considered too risky to use a human pilot. The ship fails to function as planned, and Susan Calvin persuades Gerald Black, an etherics engineer, to board the ship in order to locate the fault.
