Agreed. You could start with a set of Nanotubes as the basis for a simple 4WD or 6wheel drop center with the front wheels unpowered. With no chain and all the gearboxes enclosed (except for lightening holes) you can enclose the tubes with Lexan (or even tape if you clean it well enough) to keep the gearboxes safe and fingers out. If you add fenders over the wheels and a solid belly pan, that should keep most of the crud out.
I won't speak to the electrical side, as others are much more qualified.
We're working on this approach for a baseball pitching robot at the request of the local minor-league baseball team. I'll post photos when done.
