Ratchet Powered Lift

Hey Forums,
I’ve noticed alot of very effective lifts in alot of match videos, that don’t have any motors that only power the lift, but mostly ratchet powered lift from what I’m noticing (I’m guessing its a ratchet on the flywheel). I’m not sure how I would build on of these for my robot, and don’t really have a place to start. I just need some help on getting the basic idea of how to implement a ratchet into the flywheel to get the reverse motion to activate something.

Thanks

This has been discussed before in this thread.
I hope this helps.
