Code:

Missile displayed his prototype at the third Robodex event in Shinjuku on January 17-19. The event is open to "everything robots" and this Hatsune Miku is no exception. Standing at the same height at Missle, she has about 50 servo motors throughout her whole body. Her articulation is pretty impressive, as she's able to individually move or point each finger. The robot moves using motion capture technology as seen in the above video. Missile is wearing the motion-capture equipment which is then replicated by the Miku robot. The robot uses the internet, either connected or via wireless, to receive the input information.
