Another question, with the traction wheels on the outside, its possible that with a scrub-steer setup and 4wd; That the robot won't be able to turn smoothly since the wheelbase is so long. It would essentially jitter (bounce) over the ground as the side wheels move in opposite directions. Not saying it would happen to this robot, since I don't know it's final weight; but my recommendation would be to place the omni's on the outside and the traction on the interior. It's what nearly every other implementation of Butterfly uses. See this butterfly implementation
