Good catch! thanks, I will let the mechanical team know about this and we will figure something out.

We can easily change the wheels out, we would rather learn and see the differences ourselves to make our own decision. But thanks for raising that point.

If you look at the Duluth East Daredevil's robot from last year, we mounted most electronics on the vertically on the battery stack. Have you considered doing that? It might save some bellypan space, depending on what you want to use the robot for in the long term.
