Via, Akihabara News.
See what 300 Euros will buy you in Japan? Judging from another picture
on Akihabara, it seems you get about 9 servos, lots of wood, 3 battery
packs, and some sort of proprietary controller board. The results? ...
I have no idea, because the company website is in Japanese.
Looking at the PDF flier, it seems it "Greeting Stand Up" and "Walk Box
Dance". Yay!
