The positronic man

The Positronic Man is a 1992 novel by American writers Isaac Asimov and Robert Silverberg, based on Asimov's 1976 novelette "The Bicentennial Man". It is about a robot that begins to display characteristics, such as creativity, traditionally the province of humans; the robot is ultimately declared an official human being. The 1999 film Bicentennial Man, starring Robin Williams, was based both on the original story and the novel.
