We'll have the back 8"s (traction, roughtop) driven by 2 CIMs each through an AM toughbox, the front not driven. Chances are, our hurdling device will be mounted on the "back", making it the front. Battery will go on omni side, then, to reduce chance of tipping.
We've built the kitbot chassis part, and are ordering the wheels / extra CIMs / etc.
This took probably 3x as long to model as it will have to build. It was my first time using CAD.
Thanks, SolidWorks!
Edit / Note: These all may be upside down, as we may flip this over for a lower COG / wheelbase... depends on how easy it is to mount the Toughboxes that way, though.
