We have hexus.tv cover the most amusing though slightly dodgy sex robot but really it's not that great.
So instead I bring to you what some crazy person has achieved. Being rather upset that their Super Dollfie doesn't move or dance, they rebuilt it in robotic form.

P.S. I am very sure I saw Super Dollfies whilst in Tokyo (I was in one of Volks shops, the people who make/sell them) and they had HEFTY price tags. Personally I don't see the appeal of them but making one dance is just uber cool
