I like how organized everything is, even on a congested electronics board.

I also like how the 80/20 'standoffs' are tapped for bolts for easy attachment of the outer side rails. Even better is that these 80/20 pieces could easily serve as chain tensioner mounts for a light-weight chain tensioner, should the design not have an auto-tension system.

Only criticism (and it's small!): I don't think it has enough ground clearance to traverse an elevated field component, nor is this particular design versatile enough to easily change a component to allow it to.

Great work!
