We have named him Adrian in honor of one of our young alumni mentors that passed away in June of last year. He was the one responsible for solving our biggest consistency issues with last years can grabbers the day before we packed up for Champs. He was also the mentor I worked along side of the most working with our Mechanical Design and Fabrication sub-teams last year. The last time I saw him was when we wrapped up after picking up and unloading the 5 big machines we got a couple of days earlier. I am sad that I wasn't able to work with him this season on improving our shop and training our students. He will be greatly missed.

EDIT: also the stuff Mike said
-------------------------------------------------------------------------------------

When we started working on the 2 ball auto we were getting times of around 23 seconds for the full cycle. We managed to shave 9 seconds off of that time(And we could have done more!!!)*

*well probably not any meaningful amount of time

Re: 1678 Two Ball Auto

Will you guys be releasing an unedited version of this video after your first competition?

This. We have Utah the same as CVR so I won't be able to watch it live.
As a side note I find it a little ironic that the same people who condemmned 5817 for hiding a shooter prototype early-season are hiding their ~~robot~~ bench grinder now, when it's too late to make significant design changes. An unedited version after CVR would be neat.

Jesus christ.... please have mercy on the central valley....

Re: 1678 Two Ball Auto

Is there any reason you guys shoot the ball on the field first, and then use the ball you started with?

That's American GP.

Re: 1678 Two Ball Auto

me walking into this thread after being at work and meetings all day

Congrats to 1678 for managing to build a team that has developed a concentrated level of what is likely insanity-based-dedication across a wide group of people. Win world champs and you can take the first 15 weeks of the season at a slowly increasing pace instead of blistering, right? Guess that's not the attitude y'all have.

By the way, well done 1678. Impressed yet again.

The placement of that boulder on the center line is in a location that could hinder the other alliance from crossing a defense should they choose that, as the secret passage is directly in front and not a defense. So it comes down to do I stop them from scoring 10 points or do I score 10 points, also do I risk hitting them if we go for that ball at the same time?

Also awesome auto, though i don't think that bench grinder is a legal FRC robot.

I don't think dropping the first ball is motivated by wanting to "steal" it from the opposing alliance. They're simply putting their starting ball in a place where they have significantly more leeway on the 2nd run without getting a penalty. Why risk trying to get within 2" of a spot after crossing defenses if you can be much more reliable doing it BEFORE you cross any defenses.

1678 looked at the problem, and found a way to solve it that should be significantly less risky. If they miss the 2nd ball on the way back, oh well, but at least they're much less likely to get a penalty while doing it. Pure genius, and major kudos.

P.S. How long until you can do 3? :-P

I still think the dropping of the first boulder is super key. If you shoot your starting boulder first, you run into a huge problem. How do you approach the midline with enough precision to grab that second boulder, but not get a penalty for crossing the midline in auto. That's a very tall order for a dead-reckoning or vision-tracking robot, which may not know where it is at all times.

Drop your starting boulder far away from the midline, and you don't have to be nearly as precise.

Quoted relevant points from this thread.

We are humbled to carry on his legacy through a program he loved so much.

Do well Adrian!

Re: 1678 Two Ball Auto

Now imagine if you had two robots like this on one alliance! 60 point auto, not even counting the third robot, so potentially 70 or 80 point. In addition, the 4 balls scored in auto and the minimum 3 balls starting in the castle means that the opposing HP is forced to release at least 1 ball at the beginning of tele-op. At that moment, all opposing robots will be on the other end of the field, allowing this ridiculously overpowered alliance to grab the boulders off the secret passage without interference. This alliance would have a HUGE lead in points and cycle time!:ahh:

Maybe I will to see this at IRI or on the Einstein field. One can hope...:]

To make this possible, one of the autonomous routines must be performed on a non-low bar defense. 1678, your move.;)

Cross a Defense: Dukes of Easy mode
1 Ball Auto: Hard mode
2 Ball Auto: Harder mode
3 Ball Auto: Hardererest mode
4 Ball Auto: God Mode

I will bet a 2 inch Turner's Cube that we won't see a successful 3 ball auto all season in a match. A 4 inch Turner's Cube to the team that does a 4 ball in a match, and me wasting hours on figuring out how you hacked the very laws of physics.

It is definitely worth coming up with a 3 ball auto to get one of these, they are absolutely fantastic. Well worth the shirt I traded at Champs last year!
