Found more info http://univ.nict.go.jp/people/xkozima/infanoid/robot-eng.html I don't want that Infanoid but Keepon can be my friend. Doesn't look like it's going to be on the shelf soon, though.
I heard it doesn't work that great and has tourble adjusting to/keeping up with beats. Then again $30,000 vs. $50 so there's gonna be some lack of features and performance.
