To save parts and ensure there are no mechanical differences, I would use the same drive base. Build a simple electrical board for it, but leave off the speed controllers. Put the speed controllers into separate boxes (even cardboard boxes would do for this), with a wiring harness coming out of it (wired up the same way for each case, so controlling the motors is identical). Close the boxes. Strap each one onto the robot sequentially, and hook up the wiring harness. Drive it around, and do an evaluation. Take the next box, and repeat.

For best results, use 3 identical boxes. After it's built, have someone randomly shuffle the boxes, then number them as you use them. That way, you won't know which is which until after your evaluation, when you open them up and compare the number to whats inside!
