We have access to a CNC mill, and we order some aluminum and cut it up there to make our rims. We then go through and cut up inclined conveyor belt which we order (I believe from McMaster.) We also anodize our rims. We then rivet on the conveyor belt, and create 6 wheels with this design. We end up placing these on our robot, and lowering the 2 middle wheels 1/4 in to allow for much better turning. We can turn on a dime with that set up, while we still have the advantages of 6 wheel drive, and we get very good traction this way.

We do this because it is light, effective, doesn't take too long to do, and it looks really nice. In testing, none of the team members could push our robot (we also had 4 motor drive) and we weren't pushed around in competition - save the one time our battery died.
