You also can run the extension and contraction ports of the cylinder at different pressures. You probably only need any substantial force in one direction.

Have you considered extending a part of your shooting arm outside the frame perimeter to use as a manipulator? You could start the shooter in a vertical position to remain inside the frame perimeter during auton. I feel like an extension with a hook at the end would have a bunch of capabilities: opening Sally Port, lowering the Cheval the Frise, pulling the drawbridge down etc. What kind of gear ratio are you running to lift the arm? It looks like 2 cims in some pretty stacked versa planetaries.

I'm not quite understanding how the hook rotate up? It looks like the cylinder just pushes the end out and the hooks don't have anything to pivot on...

So the hooks will have a cable on the very front side (there is a small hole in the cad model) but on full extension of the cylinder will cause the hook to flip out because the cable will be just long enough to cause the book to spin on its attachment bolt.

It is a 40 to 1 with a cim. We plan on running the arm to the back of the bot to use as a manipulator on some of the defenses.
