Re: pic: 1683 8 wheel drivetrain completed
Every good 4+ wheel drive train has an odd number of wheels on each side. This is because the center wheel is dropped to allow the robot to "spin on a dime" because it rocks on the center
When you start pushing someone or they start pushing you, the robot basically turns into a 4 wheel drive system by falling to one side. Either the front or back wheels barely touch the ground when this happens.
In your system here, you COULD drop the two sets of center wheels if you so desired (this is what team 48 did with their tank drive system) but i doubt it would rock very well on those four wheels unless you move them closer together.
