We found that out the hard way this year (our first time building an H-Drive), even after dropping the center wheel 1/16" we still only had enough traction to strafe about 75% of the time.

Our system, which I explain in my last post, was able to move up and down as far as it needed to get enough pressure to move the robot, whether we were on carpet or foam or solid concrete.
