This weekend took place the Maker Faire Tokyo, a fair where one of the biggest attractions has been the Kuratas, a kind of mecha-like robots developed by Suidobashi Heavy Industry. Only one of the prototypes was shown on the fair which could be used by visitors. On their website you can even buy one (a little bit over 1 millon euros/dollars).
This video explains the concept behind the Kuratas development:
And this other video explains how to use it: drive, shoot, move arms etc. It can be controlled from the inside or remotely using a smartphone.
I can picture somebody using a Kurata to film a science fiction movie without the need to use special effects 😉
