The problem you may encounter is turning ability. It would be smart to take this into consideration when designing your chassis.

If this Tshirt cannon bot will be driven outdoors on the grass and dirt of a football field, you'll probably want something more than the belting you may have seen used on FRC robots. I'd recommend snowblower treads. I know 171 used them on their 2002 robot and they worked perfectly fine.

You'll want to make sure the belts are well tensioned and take lateral slip into account (making sure they don't jump their pulleys).
