Reversible Bumper Update

[scaryone]

I asked a follow up question this morning. I think they are saying reversible bumpers are ok, but why not just say three layers is ok.

Can you post the question number?

As for 3 layers versus 2, it's starting to look like they are saying add-on covers are ok (2 layers), but reversible are not (3 layers).

Also, Q17 seems to imply that reversible bumpers are allowed.

Q377

[DonRotolo]

OK so Q377 was asked specifically mentoning "3 layers", the answer was "see update 2-21". That update specifically mentions 2 layers.

So if I am reading this correctly, folding the fabric over (thus creating 3 layers) is not legal.

Oh crud.

Other opinions?

I agree, seems like it is being ruled illegal. Has that rule been similarly phrased all season? I think a lot of teams, including 694, may be in big trouble as the rules are phrased right now.

two layers of cloth and seams are is permitted if needed to accomodate R27, provided the cross section of Figure 4-8 is not significantly altered).

I would agree with Jon that the flip portion should be counted as one layer since they are permanently joined (not that my opinion matters vs. the GDC's).

Wouldn't permitting only 2 strict layers of fabric also prevent a team from folding in the raw edges of the base fabric if they intended to use any covers, or creating a folded pocket on covers/reversibles for elastic material?

I don't see how having a few extra layers would significantly alter the cross section either, and hope the GDC clarifies soon.

Note that update 2-21 added "and seams are". The two layers wording was added in update 2-11, in which tape was deemed legal.

Wondering what in the world made First put the "2 layer" part in the rule anyway. Is there some sort of competitive advantage to having 6 layers or something?

But, again, thanks

Q404 Q. The update does not seem to cover the question. Reversible bumpers require 3 layers of cloth. Does the update mean that two layers sewn together equal one layer of cloth?
Answer is in pending state

[mcason]

Update 2-25-14 made reversible bumpers legal again.

[Mastonevich]

D. be covered with a rugged, smooth cloth (multiple layers of cloth and seams are permitted if needed to accomodate R27, provided the cross section of Figure 4-8 is not significantly altered).

R27




Each ROBOT must be able to display red or blue BUMPERS to match their ALLIANCE color, as assigned in the MATCH schedule distributed at the event (reference Section 5.1.1: MATCH Schedules). Markings visible when installed on the ROBOT, other than those explicitly required per R28, are prohibited.

So I didn't have to take our bumpers apart and rebuild them? I should have just left them alone? Is that what you are saying?


Just kidding. I'm good.
