Stage suction climber?

[nhos]

Out of curiosity, is anyone considering doing a suction climber for Crescendo? I did a preliminary search and didn’t think I saw anything recently posted. Since you are able to contact the “chain-facing vertical surfaces of the core (with regards to the chain used by the ONSTAGE
ROBOT, green shaded elements in Figure 6-3)”, it seems like this would be a perfect flat surface that you could you use something similar to 2019, but just attach vertically? This would give you a lot more predictability in your climb and possibly make it easier to reach the trap. You could even have a little arm drop out of the robot to lay on the chain so that you are partially “supported” by it for harmony points.

I guess the downside is that maybe the stage structure doesn’t seem like it really is built of this and maybe could cause damage to the structure/penalties?

Rule G415 maybe?

[w4drone]

that seems worded to prevent vacuum suction against the carpet only

[dan]

“including”, but not limited to.

[nhos]

It does seem like it is worded for “ARENA elements”, so I guess this does rule out the vacuum climb.

[Skyehawk]

Having done vacuum stuff I would advise avoiding this rabbit hole unless you have developed it before and know the quirks.

[w4drone]

that seems like its specifically limiting different ways to fasten to the carpet. It doesnt really read like they are limiting vacuum interaction with other field elements

[kingc95]

I don’t know if I would trust the fasteners holding that panel on to support the weight of a robot hanging from it. My guess is they didn’t want teams to hang from the vertical faces of the stage and didn’t design for it. It’s 8 1/4-20 bolts. It’s better than my initial guess of rivets, but still seems like you could snap the panel if you were pulling hard enough

[nhos]

But I think everything on the list is all in reference to the top of the section. The parentheses are just an example I think.

[justicht]

Ignore the parenthesis, and read the full rule again. I think you’ll find that attaching to field elements is against that rule.

[JeffB]

You’re not reading this correctly. The rule itself states “with ARENA elements” giving an exception for the chain and GAME PIECES.

“Attaching to” applies to that rule meaning all ARENA elements.

As there was confusion as to whether or not doing something to anchor to the carpet would be considered here, that was added to help clarify that’s inclusive to this rule. It doesn’t explicitly state that C only applies to the FIELD carpet. It just points out this is part of the inclusion.

Though, let’s say your interpretation was correct. E would also cause a violation.

All of that to say, I expect the chain bit to become a requirement for the climb at some point to close up some pretty nasty loopholes that currently exist. This isn’t really a place you’d want to focus too much of your time.

[RoboChair]

The way the rule reads in its whole is that you may only grab, grasp, attach to, become entangled with, and suspend from the chain. If you are talking about the truss, the alliance wall, the stage core, or any other part of the field other than the chain you are not allowed to use those listed adjectives.

[w4drone]

oop im bad at reading, ignore me

[Steven_Carmain]

Remember you can do stuff like push on the center part of stage or drive up it (like 2481).

There are some out of the box solutions to the trap, just haven’t seen one work yet. I’ve seen some teams pushing on the bottom of center stage too.

The closest I’ve seen to a functional trap design is https://www.youtube.com/live/mHuHVt2AsmY?si=twFWahy60KycvK79 (start at 2:20). It works, but basically redesigns your whole robot.

[kingc95]

Team Update 2 has more info about this I believe, given you can be touching the flaps while on the e chain maybe they are less worried about the weight than I thought. Still not clear.

[Steven_Carmain]

I don’t think that update applies here. That update tells you how you score at the end of the match and what will score at the end.

It doesn’t mentioned anything what you can do during the match to score in the trap, and what you can/can’t attach to or use.

[kingc95]

Not attachment I agree, but the note about being in contact with even the vertical faces of the trap while on the chain negates my earlier part about them not planning that part of the field to have Robots hanging on it or hitting it.

My worry was more about of the vertical panels are gonna hold up if you attached to it. If they aren’t worried even about the trap during the scoring then they must not be worried about robots running into it while swinging around on the chain. If it can take a hit one way it can probably survive pulling the other way more than I thought.
