Pink Tentacle reports that some bunraku robots from 1970 World Expo in Osaka have been restored for an exhibition at the National Science Museum in Tokyo.
Modeled after classic bunraku puppets, each pre-programmed robot is driven by around 20 pneumatic cylinders that move the arms, torso, head and face in sync with accompanying audio.
The video above shows one that transforms into a demon.
