The point of this is so that each wheel's axis will point to the center of rotation of the vehicle so that the wheels do not scrub.

3) Not sure I understand what you mean by "omnidrive, with each wheel receiving the same value from the joystick". Each wheel of an omnidirectional vehicle typically receives different commands, not the same commands.

I apologize. I was confused myself when I was talking. We had standard wheels. In "Ackermann" the wheels turned opposite of each other to make tighter turns. In "Omni", say you pushed the joystick to the left. Each of the four wheels would go left. Up-left, each would go up-left.
