Yes, I'm as shocked as you are here, I just got the CAD this morning
The hardest part is figuring out how to balance out c.g., but there are also other things to think about. We originally had an idea that battery would be on one side of the wide-drive bot and all motors would be on the other side. Now it looks like electronics and the battery will go on one side (to keep the 6AWG wire short) and ... who know what else on the other. Well maybe we want the battery and electronics on the same side, but not so close that someone accidentally knocks into something while changing the battery. Perhaps we'll put the bridge lowering device opposite the electronics and the battery for partial c.g. offset.

Yet if we put the electronics on one side and the motors on the other, won't we need large channels for all of the power cable runs? Well what if we put the electronics board vertically on the back? Then the drivers can't see how many balls they have when the robot faces the other way to score. So maybe we stick to the side.

What about both sides, and a split electronics board? Nope, can't do that because we promised ourselves it's been more of a nightmare than a blessing in the last 2 years. Still need a large wire channel and it's simply harder to figure out what wires go where. Keep everything on 1 board, or at least 1 assembly.

There are miles and miles of questions, decisions, and tradeoffs. Yet as we lay them out we're realizing that they aren't insurmountable or overwhelming, which means they're within our capabilities.
