I only recall one time where we had to chase a wayward auto ball for more than a few seconds. Our pickup roller was somehow still in the track of our launcher; it started upright to be within the frame perimeter. The ball went backwards (not quite a reverse truss shot). If it had happened in teleop, the effect would have been the same.

I guess if you had a low percentage auto, it was not worth loading them at all in 2014, or stuffing them in the low goal. If you were much over 60%, the risk was more than justified. And even a box on wheels should be able to a score a low goal auto pretty consistently.


OK, I missed that. I don't remember passing balls between robots being illegal, but I don't recall it ever happening, either. Or is this something else?

This was a difference in teleop, not auto. The key was protected whether the balls you were carrying had been preloaded in the robot (or if you didn't have any balls). In both games a loose ball was a loose ball, whether it was initially loaded in the robot; in RR it was available but not a liability, and in AA you couldn't get another ball until you scored it. The "opportunity cost" of missing a shot was usually the same whether the shot was taken in auto or teleop in both games.
Did you watch 2014 Einstein Finals-2?
Missed autonomous shots caused the 254-469-2848-74 alliance to lose a match because of how long it took them to re-score those missed balls. Whereas missed autonomous balls on Einstein in 2012 didn't mean you automatically lost the match.
What this meant was that if you messed up auto at most events during eliminations, you lost the match.

As for feeding balls to partners in 2012, 4334 did it throughout Archimedes Eliminations, as well as on Einstein. 20 did it as the third robot of the Connecticut Regional Championship alliance.

Basically the problem with 2014 autonomous was that letting your partner run their autonomous routine was a major liability if they failed, whereas in 2012 and 2013, missing auto shots just lost you that autonomous score.
