I don't like to do this but this will not work.

Those motors do 21'000 rpm ungeared. with the 14T and 36T pulley reduction the drive shafts are doing 8166RPM. With your 73mm wheels your robots top speed is 69.8mph... that is stupidly fast. That is uncontrollable to the extreme. And that isn't taking into account the speed when spinning. Most machines don't go over 10 or 12mph.

I have used that accelerometer in university projects and you will require custom programming to make it work with your set up. That in itself may be months of work to make sure it is safe and reliable. You will need an on board processor as well. If that gets damaged your machine will be useless.

Finally, going by the name you have found the US bot 'Death by translation'. That machine took 3 years to build by 2 very experienced engineers and a dedicated software programmer. And after all that it wasn't very effective, even in a large arena. In the Robochallenge arena you will never get it up to speed before you are hit by another robot.

Full marks for trying to be different but there are a whole bunch of reasons why no one has bothered.
