Here, I completely disagree.
A well designed 4WD robot can have as much traction as a 6 or 8 or 14 wheel drive robot.
Coefficient of friction is Coefficient of friction. Contact patch size or number of wheels or whether the starts are aligned has nothing to do with traction. The only 2 things that do are Cof (Mu) and maintaining contact with the surface in question.
The only advantage that a 6WD robot can produce is a shorter wheelbase ... and that can be mimic'd on a 4wd robot by driving wide instead of long.
