Re: Team 2594's shooter prototype
Things to watch for in this design:
-The hopper is borderline unusable in its current state. It's going to be jam city at the feed hole, so make sure you account for that in your next revisions. I recommend using an "active hopper" or at least have a functional agitation system to keep the balls feeding nicely. Look at some paintball hoppers for inspiration, they've tackled that problem quite nicely in the last decade.
-The geneva mechanism can easily jam if it runs too fast, or allow multiple balls through (which i'm not sure you want or not) if it moves too slow. Either way, ball pinching might pose a very significant problem for you. I like the idea though, work on its implementation
-In the current orientation, it looks like it's only possible for you to score in the bottom hoop. While that isn't a bad thing, it is unfortunate that you limit yourself to that one hoop with a mechanism that cannot impart any backspin on the ball, and will be shooting balls at a flat angle right into the backboard (which is probable that the ball will just rebound off and miss the rim) If you move the rollers real slow, then why go with 2 FP's (which I assume you're modelling with cims for easy cadding). In all, the shooter choice just doesn't seem to mesh with your strategy.
Good luck with your future iterations, and remember to prototype these things out! I'd love to see a working geneva ballfeeding mechanism
