But I haven't seen anyone discuss how you can implement these ideas. Anyone done this before and have details/pics they can share?
(note, I'm not a mechanical type.. i do software, just trying to get ideas to share with my team).
THanks.

We used a disc brake on our 2014 shooter and found it very easy to work with. You can check out our CAD for details of how we implemented it. We used pneumatic to pull the cable, but you could just as easily use a spool or leaver arm on a very large versa planetary reduction to pull (I think you could do an over-center linkage thing with a hard stop kinda like the cho-cho linkage to have no holding current and make the software pretty easy). You would have to do the math on those details.
