EV rules are relatively unchanged in 2009. EVs now have to be shorter and thus less accurate. Mechanical EVs now have slight bonuses, but I believe good electronic EVs are still going to do better. Anyways, I welcome these changes because they level the playing field, and it'll be be easier to find boxes to fit EVs into.
I think I will be using one continuous rotation servo (Vex gearmotors are based off of these) to belt drive a plastic chassis with a steel shafts/ball bearings/CD wheels "drivetrain." I'll probably switch the driving pair of the wheels to pulley/o-ring wheels at some point. I may use a rifle scope to aim, but I find that it's pretty useless.
So, what are your designs going to look like this year? Will you be using Vex or a robot kit or building your own frame? Are you going to use wingnuts, timers or optical encoders? How are you going to aim and brake the vehicle?
