That was Awesome!

Great technique by the human player. We'll be using this as a training video.

GTR West Q49. The blue alliance just executed a beautiful strategy with 3 weak robots and succeeded in 2 31pt cycles.

I'll be showing this video to my team ... and ALL of our alliance partners.

Thanks for the link

"6061 is highly weldable, for example using tungsten inert gas welding (TIG) or metal inert gas welding (MIG). Typically, after welding, the properties near the weld are those of 6061-O, a loss of strength of around 80%. The material can be re-heat-treated to restore -T4 or -T6 temper for the whole piece. 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.

In this particular example they also ground most of the weld away. It is not surprising that this joint failed.

Just watched a rather amazing match at GTR.
Match 59: 1310 facing off against 610 (&Company)

1310 beats 610 by a score of 161/160 to clinch the number 1 seed. :yikes:

It will be interesting to see who gets picked. :cool:

I'm more amazed by the poor defense being played than anything else. The blue alliance was certainly efficient, and certainly had two extremely capable robots, but it should have been trivial for a red robot(s) to shove one or both of the blue robots out of alignment.

12.4% of winning alliances would not have won without penalty points? That's insanely high. If I am reading this correct and that is only the qualification matches being taken into account, I would be interested in seeing that same statistic for the eliminations.

Agreed. I haven't watched any streams, but it sounds like penalties are huge in a lot of places.

Not all eliminations matches have taken place yet, but it's currently around 9.8% of matches that were won by penalties.

For comparison, it was 3.9% of (all) matches last year.

You're right, defense is most of the time pretty easy for stopping the catch, but we were paired with a large bot with a great shooter and 1772 had a strong drive train; it was pretty difficult to move around. Nevertheless, still the highest score in the world right now without penalties I believe.

Yeah, I'm reasonably sure it's the high-high score no questions asked.

At any rate, I point it out not to take anything away from you guys' win (based on that video it's difficult to imagine a world in which you didn't win, defense or not), but mostly just because it's another important conclusion to be drawn.

There's a big reason why this game is so physical, and that match proves it.

10% isn't ridiculous compared to some older games though. This was back when they penalties and subtracted from your score, instead of added to your opponents score.

You're completely right! This match is incredibly physical. Our executive captain pointed it out to me that it's an open field, and a you can do a lot on an open field to damage other robots; ramming at full speed, pickup arms and shooters will be hit from the side, and huge balls falling from the sky are all parts of this game. That may be another reason they increased the weight limit of spare parts. At Palmetto, I saw some serious aggressive driving, and I fear that this type of driving may become integrated into the game.
