Who gets to determine if said mechanism is safe?
If said mechanism is safe, what if it was <.5s?
What about <0.25s?
What about<0.1s?

There could be a lot of energy involved in moving a "robust, strong, arm" that quickly.

Of course, if you ever come up against a faster arm, the solution is: more energy. What an interesting dilemma we all face.

Thankfully there is an awesome spreadsheet for determining which motors and gearboxes to use to make the arm move that fast!

What?! Really?! If only I had known...

I suppose that the LRI will get to determine if the mechanism is safe or not. Quickly-moving, robust, arms have been a staple of many FRC games, so I would note that precedent for similar arms exists.

There will certainly be a lot of energy involved in moving such an arm, just as there will be in any mechanism that can quickly manipulate this game's relatively massive scoring pieces.

And, of course, any driving robot will contain a whole lot of energy. But generally people seem to ignore that sort of danger because their used to it!
