Treds work good
 

I'm from SparX (1126) buckeye regional champs, (thank you 541, 27 and 191) and we found that treads work great for us. They kept us on the top nicely and we really didn't have a need for hairpin turns. When we were on the top of the ramp we seemed to push over the bots with wheels the easiest.

Belt
 

We also went with the Brecoflex SuperGrip belt. After one practice round, I noticed that the belt was damaged. I thought that another robot had done it, but now I know, that ramp is dangerous. Later in the day it got, the more "white" (Speaking of the color, under the green grip)

Now, I don't think it is going to hold up to GLR, and The Championship Event.

I "think" we have spare belts, but I'm not sure... I KNOW we don't have enough money for more belts...time for fundraising....

Wheels instead of Treads
 

For this years game we did not see an advantage with treads. Treads for a robot that has a low center of gravity has been proven to be extremely powerful. For this game we did not plan to push other people around like we did last year, so we designed a drive-train that let us be very agile and quick. We used 6 inch pneumatic wheels because to incorporate treads into our drive-train it would be very difficult. Also we wanted to be fast, accurate, and agile. We also chose treads because wheels have been easier to change out if we had to for some reason.

We've never used treads because of the problems we've seen other teams have with treads. In the past, we've pushed teams so hard their treads came off, so that's been a big reason for us not to go with treads. We've used tread-like material on our wheels, though, to great success. When it's epoxied to solid aluminum, it doesn't slip off quite as easily...
