It describes the many robots at work around at the time (1963) including thermostats, parking meters, etc., and points out that they may not be recognized as such because they don't resemble the hulking iron giants of science fiction movies and TV. So far, so good. But check out this closing passage:
Update: Do I have the best readers and commenters ever? Richard Bensam points out this article in Slate on the way the story evolved (a misfired gun which wounded nobody becomes "his robot shot him"), and David Kilmer contributes this page from an Ogden, Utah newspaper which shows how sensationalized the story became. I particularly love the photo of Alpha with the dancing girls. Of course, the iron club and the "fact" that the inventor was killed are more recent additions to the myth.
Diane points to a story by the Binder brothers (Otto and Earl) which also has a similar plot:
Soon afterwards, a heavy object falls on Dr. Link by accident and kills him. His housekeeper instantly assumes that the robot has murdered Dr. Link, and calls in armed men to hunt it down and destroy it.
