GDC cylinder answer on Q&A

[martin417]

I read this answer with confusion, and when this answer came out I was truly baffled.


For clarification, I am not affiliated with the team asking the questions, and don't plan to implement this on our robot.

I don't recall the GDC ruling that something is not permitted without backing that up with a rule that is violated. I don't see any rule that requires a cylinder to connected to a valve at all. If such a rule existed, a team could connect the cylinder to a valve and just not activate that valve.

And what about single acting cylinders? if one wanted to use a spring to retract a cylinder, one would not need to connect the rod end to a valve. Is that also illegal?

Does anyone see the logic here? Or am I missing something?
