Okay, with the 2003 robot, "The Raging Squid," Team Fusion used belt drive. The advantages to belt drives are weight and responsiveness (lack of slack like with chains). However... the belt drive slips so much that there is no way that it could compete with our 2005 or 2006 robot in a pushing contest. As with chain, you usually don't have to worry about slippage or it snapping like with belts, but of course with chain, you must use metal sprockets and the metal chain weight quite a bit. We use #25 chain for our robots to cut the weight and we have not had any of our chains break in the past 2 year.
