Sword-swinging Robo-One robot

Giant fighting robots in Japanese science fiction never seem able to finish the job with guns and missiles alone — sooner or later, they have to get in close, pull out a sword, and settle things medieval style.  A new Robo-One style robot demonstrated at Maker Faire Tokyo 2012 can do just that.  Check out the cool new video caught by Lem Fugitt of Robots-Dreams fame:

Personally, I love this.  When robots step into the ring, I think any melee weapons should be allowed, provided the bots start empty handed, only equipping the weapon after the battle begins.  Robo-kendo, anyone?

P.S. If anybody can identify the builder or his robot, please post in the comments below!
