Thanks, all!

We plan on only deploying the ram immediately before pushing down the bridge, so it will be stowed and protected for most of the match. The locking plate is servo-actuated, so the arm can be retracted, which will be useful when trying to cram robots onto the bridge.

I can't show the loader quite yet, mostly because the current system uses about a dozen clamps and two feet of duct tape. Our tests showed that the variable with the greatest impact on shot accuracy was feed speed, so the challenge was to design an automated system that could load balls at a constant and precise rate. We're shooting within a 9-inch diameter circle with our current system at a distance of 20 feet, so the trick will probably be making an accurate targeting program to match.

We'll have a belly pan to keep things out of the robot and guards around all the places balls aren't meant to go, while the bumpers will be mounted at the absolute minimum height needed to cross the bump. While there will certainly be balls scattered around the field, we won't be seeing balls absolutely everywhere like in Lunacy. It should be reasonably easy to find a crossing point that doesn't have balls in the way.
