I have heard of these robots and auto driving cars. Both of these have pretty strong limitations regarding their ability to affect the environment as much as a human can. Typically these robots are heavily limited by battery usage and need to be close by to a source of electrical power. They also lack the ability to repair themselves, or construct new robots. A full fledged robot ecosystem with robots building other robots building other robots without any human intervention is a long way away, and is essential for these kind of scenarios that AI Doomsayers naively propose. The assumption seems to be that, if one builds the brain of the robot, the body and the hands, the heart and the lungs, will just all spontaneously fall into place.
