i've found that a few layers of duct tape on the wheels makes their traction better, as well as improving the wear / use ratio on asphalt. also, outside of competition, you can use any 12 volt battery (the system will run fine for hours on a 12V car batt)

t-shirt cannons plus candy = good (candycannon), mount it to the robot on a spike relay, and if you have pneumatics, interconnect them so that you can use the bot compressor

another option for power is to use a really (25+ feet) long wire plugged into the 12 volt outlet in a car (if you can drive a car behind the bot)

this year's drive station runs 12 volt. mk batteries work great for it (runs for days)

another thing to remeber: stop every once and a while and check crutial bolts / connectors, driving on the road causes alot of vibration, ans you don't want stuff falling out while you're driving.

should be fun no matter how you do it.
