There is no toe in unless something got bent, maybe I had better check! But seriously no toe in or out is not required to make the robot maneuverable.

The six wheel drive is the best system we have found so far it is simple, light, maintenance free, very little loss of horse power due to mechanical friction, and you will get the same traction as any other system.

Many people think you get better traction with a track system, not true. The only two things that effect traction are weight and the coefficient of friction of the treads. Surface area is not part of the formula. Ask your engineer.
