The Amazing Mr. Woo and His Astonishing Robots
Here's a British news report of an untrained peasant farmer who builds working robots. The robots get more fantastic as the video proceeds, especially when you consider that he builds these things from junk that people throw away. With formal training, this guy would be running Carnegie-Mellon.
He burned his house down while building robots. His wife thought of leaving him because of his obsession with robots. This guy needs an NXT.
