We haven't figured out auto-loading yet. A belt-type ball elevator is pretty simple. The tricky part is getting it from the top of the elevator to the "cup", one at a time.

Controlling distance is another challenge. We might preload the rubber tubing by winding it up around a spool with a revolution counter. And/or adjusting the air pressure. I wonder if we're allowed to use electronically-controlled pressure regulators?

This is getting complicated. A spinning wheel launcher is pretty simple.
