What I would not want to happen is for a mechanism to be deemed illegal when an inspector's opinion is that it is not safe. That's not a good way to go about this. Thoughts?

Have you not run into this in any prior year? I've put extra shields on mechanisms to have an inspector call the robot safe multiple times. The worst is when a different inspector comes over to do the final check off and says, "That really wasn't necessary, why'd you waste an hour doing that?"
With
our single mechanism collect and throw, we had lots of problems with throwing chain and having a closed loop control law to hold the arm up. I'd be curious to know how you're going about collection, especially since the ratchet will only let you go one way. Our control law had a "home" collect position, and the driver could control the position from there with joystick inputs.
