At Hyper Base, scientists were working to develop the hyperspace drive.Gerald Black, lost his temper, told the robot to get lost. Obeying the order literally, it hid itself. It was then up to Dr.Susan Calvin, and PeterBogert, to find it. They even knew exactly where it was. But this particular robot was different. Therefore, it could stand by and allow a human to be hurt. However, Dr. Calvin added further urgency by postulating a situation whereby the altered law could allow the robot to harm or even kill a person. The robot could drop a weight on a human below that it knew it could catch before it injured the potential victim. After interviewing, Dr. Calvin started growing desperate feeling that the robot might be gaining a superiority complex that might allow it to directly hurt a human. Dr. Calvin put herself in danger but not before ensuring the robots understand that if there was any radiation between herself and the robots, they would be unable to save her even if they tried. Once the test was run, all of the other robots could not identify what type of radiation was being used. The robot found himself discovered, explained that the only way to prove itself better than a human was by never being found, and it tried to attack Dr. Calvin so that she couldn’t reveal she found the robot. Black and Bogert applied gamma rays on the robot, destroying it before it could harm her.
