They have cleverly used the rat's tail to provide a flexible drive for the screwdriver, allowing you to reach those niggly screws in hard-to-reach places.
Nice for tool nerds.


It's kindof like a baby brother of the Kaoss pad and has the advantage that it runs on batteries.
The Robosapien is one of these which I imagine would be quite disappointing after the initial interest. I mean, come on, it's not really a robot is it? it's just a RC car with legs. When we think of a home robot, what we really want is something like the teddy bear in the film "A.I.", or at least the Honda Asimo or Sony Qrio - but unless you can afford to spend the price of a luxury car, you won't get one. 
Dig deeper into your pockets (around £800) and maybe you can afford to buy the Robonova-1. This little guy is truly amazing and has some really fluid movements. You can buy it pre-assembled or in kit form to save a few quid. The real advantage seems to be the fact that all the components can be sourced separately, plus you can buy some add-ons like motion sensors, sound sensors, gripping hands etc. I can see this approach being the way the market moves, as inevitably your robot is at some point going to tumble down the stairs and break a limb. It's a lot cheaper to replace a part than a whole unit.
