Never tried to "drive" a robot in the parade--it rides on the float..

If we did, the first thing is wheels--only use ones that won't be needed again;
next tape over any air vents that might get junk in them as long as it's cool outside.
Also, obviously, you're thinking this will wear out belts. Removing them would be a pain, but you don't need six-wheel drive in a parade.
