You can see a movie of it here.

Sony is also progressing with their robot called QRIO.

TU Delft is also working on a robot, but their robot works a little bit different, as you can see here.

Ofcourse there are a lot more robots being developed by companies and Plyojump gives a good overview.

And if you all like this stuff, you can build a very cool robot yourself. Look here for a do-it-yourself bot called Kondo.
