I suspect that you are not familiar with the FIRST competiton.

We use (and are limited to) the motors provided in our basic kit of parts. Because FIRST is an organized competition, we build along certain guidelines. These being our dimensional limits and our weight limit. If you are building for FIRST, you know what you can and can not use, and how much weight you have to work with, if you are not building for a FIRST competition, we need more specifics. Plenty of people on these boards know a thing or two about motors, but we need to know how much weight you really have to work with. There are all numbers of different motors that weigh less than 1.5 lbs. We also need to know how big you plan to make your robot, as well as the desireable speeds you are seeking.

Hope we can help you.
