I don't think I've seen a single team line up their robot in front of their opponent's secret passage, nor have I seen any counter-autonomous modes just to stop that one ball from being scored. After all, the crossing points they lose is equal to the points they deny in the two ball auto routine anyway. It is definitely done this way to require less accuracy and less chance of a penalty after the first ball is scored.

Congratulations to another team that's been able to make the two-ball!! Hope you can make it work at CMP too.

This is definitely the reason all two-ball teams drop their starting ball to score the midline ball first.

Tall robots with high powered turrets and fast intakes and ball transportation from intake -> shooter would be perfect for this. And it would make defense selection interesting

Very impressive! I have a question though. How is this accomplished? Is it simply that ball ends up in nearly the same place every time, or is it using some sort of shape-tracking software to locate the ball? I assume, based on the straight path of the robot, that it is the former, but I wanted to be certain. Good job guys, and keep up the great work!

Yes, the ball drop and roll against the wall is very consistent in where it comes to a stop. Ours usually roll to a stop within an area about 18 inches square.

If dropped very consistently the ball comes to rest in a fairly repeatable spot, within the width of the intake.

That's very interesting! I have seen the other previews of two ball autos (254, 1678, etc) and they all seem to be similar. I am honestly very excited to see these face off at the championships and I believe you guys are up there with the best of them! Great job and good luck!

This is awesome! Really clever solution to pinch the ball like that at the start. Looking forward to seeing you at worlds!

Not really related, but as another team using the same times as you are (albeit ours are yellow) in an 8WD configuration, I'm curious what pressures you're running your wheels at.

Sweet auto! I'm impressed. I've always admired the bots 1986 makes ever since I noticed them at newton in 2013. I'm hoping we end up in the same division this year. See you guys at worlds regardless.

30 psi in the dropped center 4 and 20 psi in the corners.

I had a funny feeling that you guys would pull out a 2 ball auto. Very impressed with the machine. Can't wait to see you guys in action at champs!

This is fantastic can't wait to see this in a match.

Nice job guys, welcome to the club.

It could just be because of the perspective of the video but it looks like your pickup roller enters "the volume above the midline" when you pickup the ball. Wouldn't this draw a foul based on G13?

G13 During AUTO, ROBOTS may not enter the volume above the MIDLINE.
Violation: FOUL. If contact is made with an opponent ROBOT beyond the MIDLINE (either direct contact or transitive contact through a BOULDER), an additional FOUL is assessed and the opponent ROBOT is immediately awarded the CROSSING of the closest DEFENSE from the point of contact.
