"Life Hutch" av Harlan Ellison, först publicerad i april 1956-utgåvan av If. Andra på ISFDB
Citat från en sammanfattning :
Terrence, our protagonist, begins the story cornered by a robot that is attacking him whenever he moves .... Terrence uses the trick any cat owner knows, sending a beam from his flashlight toward the wall where the robot’s brain is located. Crudely responding, the robot follows the light and smashes away at the wall until it has effectively disabled itself.
