Unfortunately while we were stress testing , one of the treads came off our plaction wheel. We assumed Andymark used a epoxy of sorts to adhere the tread to the wheel, but in reality the tread is only held on by three weak staples. How are we supposed to reattach it? Andymark suggests rivets, but I wonder if that is legal due to rules about metal and the floor. Could we use regular epoxy to adhere the tread?

My other question is why did this happen. Is this a common occurrence? I assume it is because the omni's radius is about .125 smaller making them in effect travel slower at the same RPM. Could this have been that cause of the problem? Do we need to gear the omni wheels so that they are going closer to the same speed? And more importantly, why aren't 8 in wheels 8 in?

here's a picture of our bot:

it is a six wheel drive with the omnis in front and 4 plactons in the back on a pivoting drivetrain we have had no issues with the tread (just normal wear) i would recommend putting your plactons at the back so that you dont create that twisting shear between the carpet and wheel
