It takes coordination, which may be difficult, but it is a safer alternative and in my opinion easier to execute than picking up from the mid line as it doesn't require your autonomous to be perfect down to centimetres.

We would MUCH rather pick up from the mid-line.... It may be a bit tricky, but the boulders are in very predictable locations - which can be programmed from our shop... Coordinating such a thing with another robot would require specialization every match we attempt it (generally there would not be time) and runs the risk of mistakes. (We make plenty of mistakes with our own robot, we don't need to compound them with another team's errors.)

Yes, it requires both robots to work well, but it is doable.

Imagine this scenario: You just picked your alliance for elims. You have a lunch break before the matches start. It isn't inconceivable to get this working in that hour if the robot doing the scoring has a way of tracking balls, knowing where it is on the field, and preferably some sort of waypoint based trajectory planner to put everything together so you don't have to guess and check every step of the way.

I'm starting to think getting a G13 might be worth it.

single ball + cross = 20 points
2 balls + cross + g13 = 25 points (30 to you and 5 to the opponents)

The last boulder would give only a 5 point advantage, but you get to weaken the tower by 1 more boulder every match.

Until you start racking up yellow cards for repeated infractions of the rules.

Or... You can simply pick an alliance member who can score its own boulder while crossing a defense.....

I suspect there will be several regionals where it is impossible to draft an alliance where all 3 robots can cross a defense and score in the high goal.

Joenac says there will not be a single regional/district where an elimination alliance has 3 robots that cross a defence and score in the high goal. Joenac is considering expanding that to every event except IRI.

An auto ball is worth 10 points, and a G13 foul is worth -5 points. If teams play smart, there will be fewer than twice as many G13s as second boulders scored. I expect the actual ratio to be worse than this; teams tend to be optimistic.
