Incidentally, this paper deals mostly with the characteristics of the robot's wheels as they turn and slide on the ground, especially as that relates to turning ability. The paper doesn't go into selecting the correct ratios between individual gears, rather, it advises you that you'll want to make a few calculations to ensure that whatever you do, you make sure that your gearboxes can put out enough force to allow the robot to tank-steer. Choosing individual gears is an entire subject unto itself. You'll have to take into account everything from size and weight to cost and availability of parts (and many other factors).
