Jesse,
Here's the easiest way to make a drivetrain using the Bosch motors:
- Use the drill gear boxes provided in the kit set to LOW gear.
- Use the motor mounts and couplers provided in the kit.
- Order two 6 inch wheels from skyway, and two casters.
- hook the output of the drill gearbox (in low gear, remember), directly to the 6 inch wheels (no need for more gears or chain). Be sure to support both sides of the wheels with bearings.
- Use the casters on the other end of the robot.
This setup will give you about 9 ft/s of speed. It won't be the best drivetrain in the world, but you can compete with it. If you want to be slower, use smaller wheels. I wouldn't go much faster, especially if you're using casters - it will be very hard to control.
The key here is that you can direct drive a wheel from the drill gearbox and be at a reasonable speed, but only in low gear. This will eliminate some complexity.
Good luck.
