Are you referring to Belts as opposed to wheels in a Drive system or belts and chain as part of the drive system

Team 522 also has used belt drive in 3 out of the 4 years of their exsistance and found it to be quite dominating if you use the right belt for the right game for the right surface the robot was running on:

2001 - Their robot used belt drive
Pros: it was superior for pushing a disabled robot to the end zone for pts.
Cons: it appeared they had some issues but not major ones when the robot was run in reverse.

2003 - Their robot used belt drive
Pros: it was superior for traction & as well as being immovable when it came time to be king or in the robots case "QUEEN" of the hill.
Cons: Non really noticeable A job well done by that time.

2004 - Their robot used belt drive
Pros: same as above & it was superior for climbing capability
Cons: same as above

Some teams have their different opinions about belts: belts are good for one thing but have their defects. I would choose belt over chain any day

1) belts won't damage the playing surface but will pop the balls due to friction unlike chains which can either scratch / tear the playing surface and possible pop the balls.

2) Traction - Different belts give you different traction capability unlike chain

3) I personally think that belts are quicker to change then chain
3a) if the robot is designed a certain way the chain may not fit the same way when you first put it on - almost as if it changed its size magically - this statement is just off of speculation and not an actual fact
3b) you have to fiddle with getting the half / master link on
3c) there's the slight off set that you could lose a part critical to keeping the chain in one piece
3d) for belt drive if the robot is designed a certain way the pulley / sprocket systems can be un - bolted and removed so that you just drop the belt ride in place and bolt everything up.
3e) as said before the belt is in one piece already
3f) a part lost on the floor for a belt system can easily be spotted / replaced

Attached at the bottom are some pics i found on delphi of team 522's robots.

Don't build something because you want to; build it because you need to!

meaning don't build a belt / chain / wheeled system because you want to, build it because thats gonna be the main key in helping you win the game aside from the scoring capabilites you want your robot to have.
