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.
