B.E.A.M.-Photopopper, pretty compact (video)

This is my µ-bot. He is a pretty compact built and a very fast bot under the summer-sun. Unfortunately I made the clip a few days before, the sun has not that power anymore to drive him well... So you see him damn slow and 1 or 2 times a second popping forward. But he's still worth to be seen, I think.
