Back Driving Problems

[shanek21]

My team has been having problems with back driving on our winch system that is used to reload our launcher. We have thought of a few possible solutions to this problem, but have encountered some difficulties implementing them. We have attempted introducing a ratchet into our gearing system, but any shafts that we could use to stop back driving issues are completely round, making it difficult to attach a ratchet to. We have also considered a gate latch system using a piston as a hard stop to eliminate back drive, but we have very few pneumatic components and this sort of rig would take away our ability to execute variable shots. I was just wondering if any other teams had found creative solutions to stop back driving issues in super shifters or catapults in general or had any advice on this subject.

Thanks in advance,
Shane
