If you like your science fiction and your hairstyling in close quarters, you'll want to check out the new hair-washing robot Panasonic just unveiled.
The 16-"fingered" machine has sensors that allow it to determine the optimal pressure and technique for individual people's scalps. It can also "remember" heads, so you get a consistent wash. Unfortunately, it's only in prototype phase, and will probably be pretty pricey when it does hit the market, since it's designed to assist large numbers of people living in nursing homes. Does this kind of robot excite you, or are you holding out for an automated hairstylist?
