I doubt inspectors will allow a chain that contacts the field. Chains close enough to the circumference of the wheel as to contact the field on a bump will provide (however small) propulsive and/or braking forces to the robot. Chains are made of metal, hence they are prohibited as traction devices. I would also worry about lubricant in the chain transferring to the carpet, thus violating <R36>.

I agree. We are purchasing new gears as we speak and will be re-vamping the drive-terrain on thursday if it does in fact contact the carpet.

We too tried the belt drive system this year and it initially tested out pretty well, but when we added weight and really pushed it hard, the belts stripped out fairly quick (not all were properly tensioned). Do not even try to run belts without proper tension!!!

we're running belts this year with 2 cims and 1 fp per side and have not had any problems with them at all. We of course have them tensioned but other than that set up has been super easy and theyre much cleaner than chain.
