Hi, I think there's two rules that I think you should consider for this design:

You might be already aware of this one, but because of <GS18> in game manual II, the robot cannot contact the pull up bar before the end game. That would probably complicate the design that you're describing if your team is aiming to climb the mountain both during teleop and the end game.

I'm not too certain about the part about launching a hook, because I couldn't find anything specific that directly addresses parts of the robot that are being launched while still attached to the robot, but in game manual I, <RG11> states that parts of the robot cannot be launched.

I hope that helps!
