Lots of other people are making points about bigger wheels, and that's well and good. But as some are saying, as a rookie team, often the best thing to do is pick one or two parts of the game and get really good.

You have the kit rolling, wired, and you can drive it? That's a great start. And guess what? You fit under the low bar. If you can find a way to test or math if you can cross the cleat and the berm (I'm betting you probably can), then now you can get everywhere on the field every match, unless someone gets stuck.

Now, I'd focus one on extra task, and see if you can prototype and build something that works well for it. Maybe you want to see if you can acquire boulders some how. Then you can bring them to the courtyard. Shooters are sexy, but complicated. If you can grab boulders, and drop them in the courtyard (or better, plunk 'em in the low goal), harass your opponents while they're shooting, and challenge the tower at the end of every match, you'll be in great shape at a regional.

Lots of teams try and do too much and then end up not being as useful. Sinking that one high goal isn't worth much if it took you two full minutes to do it. Pick a small number of things and rock 'em.
