They get a little YMCA in near the end, too.
The robots involved are called QRIOs. pronounced "Curio." Think the next Aibo, but bipedal. And a few thousand dollars more expensive. The name's very appropriate.
There are more videos here, if you scroll down and click the text links below the pictures and the pink bar. The official site's here, and it's in English and has some much clearer film clips. Make sure to note that this thing can actually get back up when pushed over, and braces itself for the fall... although anyone who would push it over in the first place is sort of a dick, if you ask me.
The commerical currently airing in Japan for this thing is here.
I'd be lying if I said I wasn't impressed. Hell, it can throw a baseball and everything. But I'll be even more impressed the day they make a QRIO that can catch one.
