If you really want to improve it, add traction wheels such as ifi and a 2 speed transmission. An even better addition is directly driving the center wheels off the transmission shaft so that even if all of the chains break the robot will still be powered. This requires a little bit more work though and most likely precise machining capabilities.

Specifically, it requires a longer output shaft than any standard transmission will give you.
Usually it's just as much weight to do the bearing blocks for a direct drive setup as it is to do an AM hub with AM flat sprockets with extra chains. Since it's more difficult to do the former, most teams stick with the default method.
Team spirit is not all about the tools/noise makers. The Tigertrons didn't have any sort of noise makers. Consider other aspects of the award by making signs, mascots, cheers, and how you interact with other teams. - team222badbrad [more]
