[Jared Russell]

Awesome video! And an awesome precedent to set - this video will serve as inspiration to anyone who wants to push their minibot to the max this season!

What I saw/inferred:

* Two motors, with transmissions removed/modified/replaced with custom transmissions that are lighter, more efficient, and geared to be faster.

* Custom direct-driven wheels/rollers that I'm sure are almost weightless (they can be tiny because of the faster gearing). Going out on a limb...lexan and split surgical tubing as the tread?

* Just enough structure and electronics to hold it all together and get it to go.

In a "spec racing" competition, he/she who builds the lightest, most efficient machine wins. (Or he/she who cheats but doesn't get caught wins, but I'm sure that isn't the case with this crowd!)
