The third timeless, amazing and amusing volume of Isaac Asimov\'s robot stories. Asimov\'s Three Laws of Robotics have since been programmed into real computers at the Massachusetts Institute of Technology and used as the outline for a legal robotic charter in Korea. ROBOT TONY is the first robot designed to perform domestic duties by the US Robots and Mechanical Men Corporation. Is it Tony\'s fault that the lady of the house where he\'s field tested falls in love with him? ROBOT AL was intended for shipment to a mining outfit on the moon. Instead, he\'s loose in the mountains of Virginia...building from scraps of junk his very own, very dangerous disintegrator. ROBOT LENNY answers workaday questions in babytalk. So why is Dr Susan Calvin, the world\'s top robopsychologist, fascinated by this messed up specimen of an industrial robot?
