Here's a robot video that I found interesting:
The Maker Faire Tokyo 2012 event was absolutely packed - wall to wall - and took up all the available space at the Mirakan Science Museum in Tokyo. Navigating through the aisles was about as easy as boarding a subway at rush hour. Nevertheless, there where a wealth ton of interesting and exciting things to see and makers to talk to.
I've uploaded a number of individual videos from the event already, so this video includes some of the smaller, but still very interesting, exhibits that caught my attention at the annual event.
