Thanks for all of the replies! Thanks Nato for telling me about similar designs. They will be helpful if I run into problems.

I am progressing with the design of the robot as I await pieces to arrive. I think I will be using a set of 40 tooth gears and an NXT motor for turning the modules. I probably will use chain and the medium EV3 motor for turning the wheels. I will still have two motors left for other actions because I will control it with an EV3. After completing it, I think I will try to do some FLL missions to evaluate its viability for FLL.
