My team had our first competition of the season this weekend and our robot has an endgame that hangs on the horizontal bar to gain elevation. We ran into a problem where when the vexnet competition controller pauses the code, it releases the tension on the motors and our robot falls. Unfortunately that cost us a couple matches and I tried adjusting the code to fix this issue but no matter what I try it still had the same results. We use Vexcode V5 Blocks to program our robot. I have looked into creating a mechanical lock but an accidental button press could cause issues
Hello!
This is standard in V5 competitions. All motors are set to coast at the end of the match. What I would recommend is a climb lock similar to this: ăVEX VRCăOver Under 8223C Climb Lock. The climb lock is passive, so it allows your climbing mechanism to go up and down until it touches the elevation bar which triggers the lock. Otherwise, you would probably have to engineer some sort of pneumatic or motor ratcheting mechanism. The only other simple-ish passive locking mech would only be possible if your lift only has to go up and down for the sole purpose of hanging, in which you would just build a passive ratcheting mechanism.
Hope this helps!

It looks like it would work well. I forwarded the link to my team and they decided it would be worth a shot. I thought it was something in the code that was causing it to do that.
I donât know how to do elevation myself, but you could probably find a way to lock whatever you are using to climb.
i would recommend using a ratchet to help keep yall up if you are using motors for hang (since i have seen pneumatics being used). just a simple c channel with a motor that is binded to the D-pad should do the trick.
