Wheel Positioning

[DjScribbles]

We had a slight surprise when we got our chassis put together. We have 2 high traction 8" wheels, 2 (relatively) low traction 8" wheels, and 2 8" omni-wheels. Our original plan was to put the high-traction wheels in the rear, with the low-traction wheels in the middles and the omni wheels at the front; however the high traction wheels are a slightly taller 8" than the low traction, thanks to the thicker treads on them.

So, we've got a bit of a split on one to do with the wheels, the prevailing opinion on the team is to put the high traction wheels in the middle and the low traction wheels in the middle, but we're not all convinced, so we decided to ask CD for opinions on the optimal wheel config.

Our front end consists of a ball collector, and we will be shooting from the back (catapult like design), and the argument for the high traction wheels in the middle is to allow the robot to tip in either direction (one with good turning capabilities, and one with higher traction), however some team members are concerned about not having all 4 of the traction wheels on the ground at all times (and being easily spun out).

Thoughts?
