I'm aware of another video of this robot http://www.videosift.com/video/Yellow-Drum-Machine but it's competely different from this one. This shows off a bit more of the possibilities this invention has.

He's a bit chicken for doing this at night, but DAYMN it looks fun! Love the wattage of lights on the front of that little kart.

I checked through the search and didn't see this although it's about a year old. I misremember a Harley Davidson exec once saying "H-D isn't about motorcycles, H-D is about allowing a 46 year old CPA from Iowa to ride into a town and have people be afraid of him."

It was never if he would hit you, or how hard he did. The only question was did you even WANT to get back up again...
