I have serious doubts that this setup can actually move. Like literally, whether it will be able to translate motor power into forward motion.

I really, really hope you've tested this. Your interface between tread and pulley relying solely on friction (and not even having a V-belt interface or anything) is really, really bad as far as treads go. The suggestion to coat the pulleys in something with more friction honestly probably isn't even going to do the trick.

The moment someone T-bones you I don't see how your treads aren't immediately going to derail.

Not trying to be a jerk, just hoping you've already answered these questions so you don't show up to competition and have a season ending "OH SH**" moment.
