I remember reading about David Hanson in an earlier edition of Wired magazine. They had some eerie pictures of his robot head replete with dangling wires and looking somewhere between dead and alive. More recently, Hanson has won a $1.5 million grant to commercialize his humanoids. One of Hanson's main advances has been the material he uses to make the faces, which makes it quite realistic. If you want one of his full-sized robots, expect to pay over $100k, but a smaller, less complex bot will run $2k with hopes to eventually bring the price down to around $300.

From the article: " One of the obstacles to creating realistic human robots is a theory of psychology known as the 'uncanny valley.' The theory states that people are comfortable around robots that look like walking trash cans with gears and wires and metallic surfaces (think C3-PO from Star Wars), or cutesy toys like Furby. But as the robot's design becomes more and more human-looking, there comes a point where the machine's realism becomes creepy to real humans. "
