You have to have 2.5" diameter pool tubes, 3/4 inch plywood, Heavy Duty Nylon Fabric, and hardware. the hardware can't go past and inch away from your robot. The bumpers can not be longer than your robot dimensions and only can be 5 inches tall. They have to be 2.5 inches off of the ground when they are on your robot. And if i remember correctly it says that it has to be fastened with a bolt and fastener system.
