Re: Week 1 Analysis
 
What continues to baffle me is when human players throw the ball onto the field without even attempting to get the ball into one of their robots. The next 15 or more seconds are spent trying to recover the ball which should have never been lost in the first place.

Things for teams to learn from Week 1

1) If you can't do scoring in auto 90% of time or better then don't shoot!!

2) Teach your human players how to put a ball into a robot fast and reliably without crossing into the field and occurring a penalty.

3) Be humble- This is a role playing game just like sports. Somebody needs to play 1st base and somebody needs to be in the outfield, the outfield is just as important. If you can't do something, just realize that and make out of what you have!!

4) Know the rules!!!!

At the MAR events it looks like refs are pausing matches in the middle of teleop to discuss and assess penalties and assists...?

Someone may have already linked this...haven't read through all 16 pages. Here's the video:

Quick cycles are the key. The third team on this alliance was dead...imagine what would have been possible with an auto contribution and some defensive play from 346. They were a capable bot - played into semi finals if memory serves.

Carnage. Who's going to want to do a 3rd event before states?

Those were definitely quick cycles.

However, there wasn't any actual defense being played on the inbounding robot or the catcher; I doubt you would ever be able to easily line up like that.

Wow, I knew this game was gonna be physical but I didn't know it was gonna be THAT physical. If you need help, let me know.

Is 3824 using suction?

Yes we are! It is a great way to solidify the seal on the ball quickly, plus it adds power to our shot.

Ian, I'd LOVE to see this data run on the Centerline eliminations. I can't say for 100% certainty, but I'm not sure if the winning alliance beat their opponents on straight score even once. Can someone point me in the direction of the centerline elim data with penalties showing?

Are there any pictures of your robot anywhere?

I don't think there are pictures online yet, but you can watch us play at palmetto! Youtube channel: FIRST3824

I'll talk to our business team and we should be getting pictures up soon on our website!

The winning alliance won 3 of their 6 matches on "straight score" (both SF matches and one finals match).

Here's the data you're looking for: http://www.chiefdelphi.com/forums/fr...p?events=MICEN

Here's the Twitter data. As usual though, it's incomplete.

After welding, the material can naturally age and restore some of its strength as well. Nevertheless, the Alcoa Structural Handbook recommends the design strength of the material adjacent to the weld to be taken as 11,000 psi without proper heat treatment after the weld."

That compares to 35ksi yield strength of properly heat treated 6061-T6.

Teams that use welded aluminum construction need to realize that your welded joints are now incredibly weak. And that's if the welding has been done with perfect technique (certified welder with years of experience). High school grade workmanship will be way worse.
I believe the welds were on 6063 aluminum alloy which I believe gives us a loss of around 30%. Regardless, that's the least of our worries on drive base. No worries though, we'll be back in Virginia.

Thank you ether. Am I reading this correctly? Are rfpts and bfpts foul points, rhpts and bhpts hybrid (auto), and rtpts and btpts teleop?

If so, 25% of the points scored in the elims were fouls.
