A friend of mine is looking for a short story she and her husband remember from grade school. She says it is not Asimov. Copious Googling hasn't helped. Her description of it is: "the story is really short, and it's about the unveiling of the latest advance in robot society (the planet being wholly populated by robots now), a self-healing, organically powered robot, and as you read you realize the robots have recreated humans"
