The CIM motors work great to drive alone. We did this one year and found them to be very smooth. The downside is that they are very fast.

To calculate how to gear them down, you need to do a few things. First, decide how fast you want to move and how much force it will take to do it. Then, take the distance around the robot wheel. Knowing this, you can calculate the required rpm of the wheel shaft. Take that speed and compare it to the CIM motor. It will ikelt be many times, so you will have to do a multi speed gear reduction. This will include possible coming out of the CIM with a large gear, then attacking the large gears shaft to small sproket. Then you would attack the small sprocket to the wheel shaft (most likely with a large sprocket on it).
