Many teams will show up to regionals with nothing more than a drive train and some hooks that don't work/fail/never get deployed.
Teams need to take a long hard look at themselves in the mirror and make a realistic assessment of what they are capable of.

First had never texted actual robots on the pyramid, and when a team built the pyramid and put a old robot at around 150 pounds on it, the slide in joints at the corners started to flex and actually twist the pyramid, not so it broke but twisted in the extra space in all of the joints. I just feel like until the release something after week 1 that will strengthen the pyramid, I don wants to risk putting my robot that high in the air.

Are you talking about the team pyramid our the actual pyramid? I think the actual pyramids is one of, if not the strongest FIELD elements ever designed by FIRST

Right. I'm pretty comfortable hanging near-arbitrary FRC-scale weights off of welded 1.5" steel.

a 30 pt climber that can also harvest discs from the ground in autonomous is certainly pretty silly for 99% of teams, but having a super simple wheel shooter that can only shoot 3 discs is pretty reasonable.

Although I actually agree that the 20 pts will be able to be made up easily by great shooters.

this year, I can see the possiblity of having 3 good shooters that don't get in each other's way that much, especially in elims after some practice.
Eh, there's a way to look at it which assumes equal teleop scoring between the alliances. Do you think it's just a coincidence that a perfect autonomous (15-discs) is worth just as much as a perfect triple-30 climb? It's also not a coincidence that both are [mostly] undeniable points -- that is, there's very little that can be done defensively to deny an opponent those points. IMO, they're both equally difficult too.

Are there potentially 3 teams in the entire world who could band together to pull off 180 undeniable points? Probably -- but the selections process probably won't let that happen. I think the common elite alliance will be able to pull off roughly 120+ undeniable points at the more competitive events, depending on the tradeoffs the engineers had to make for hybrid vs specialized machines. After that it comes down to strategy and raw disc scoring ability.

With that said, specializing and doing nothing else needs to be done on a team-by-team basis. It's probably the best option for most teams (bottom 4 sigmas of a Gaussian distribution), but alas, most of those "most teams" won't do it either. You never know, specializing could also fill the niche that 2 'powerhouse' robots need in order to get to 120+.

Re: Shooting Vs. Time hanging 30
 
So which are we more likely to see first: Three teams hanging from the top or a pyramid collapse into a heap of scrap from all the weight?

Re: Shooting Vs. Time hanging 30
 
I agree with the specialization approach. And I also think that when we are evaluating what tasks most teams would be successful at specializing in, the order of tasks ends up prioritized like this:

3 pt shooting

10 pt hang

5 pt shooting

Floor pickup and shooting in autonomous

20 pt hang

30 pt hang

So the 30 pt hang should be at the bottom of the list....but maybe I just say that because I haven't figured out a way for our team to do it, after two weeks of thinking about it.

Please cite your source for this. They may not have tested robots built by teams, but I would be amazed if they did not build their own robots to test the game and ensure the pyramid was strong enough.

There are many reasons not to hang, but I do not think fear of the pyramid breaking should be one of them.

You didn't build the actual pyramid, you built the team pyramid. The actual pyramid is welded together and doesn't have wood and U-bolts holding it together.

Definitely the former. No way something built like that collapses.

I'd be willing to bet that they hung more than three competition weights on it. A steel wielded structure with the specific purpose of hanging robots on it has probably been designed, redesigned, and overdesigned.

It was not from an online source, it was a FIRST FTA.

The pipe is not the problem, the steel pipe can hold plenty of weight. The joints where the couplings slide into each other, that is the weak point.

Re: Shooting Vs. Time hanging 30
 
But looking back it wouldn't be the first time they had to redesign game after launch, logo motion for example, the pegs for hanging tubes had to be fixed

Re: Shooting Vs. Time hanging 30
 
Ok I think we are getting off topic

I think if you have three robots that just get to the 10pt thats 30pt not including shooting and auto :yikes:
