The fine folks at i3 Detroit built this giant, ridable bristlebot using a large motor, a pipe for an offset weight, and a bunch of push broom heads. They claim it is the worlds largest, which I tend to believe. Does anyone know of a larger one?

Also, I think the only proper way to respond to this is to make an even larger bristlebot and challenge them to a race. Detroit makers, you are on!
