If wrapping the noodles around corners (and thus inevitably compressing them and distorting their cross-section in violation of the rules as presently stated) is legal, then Fig 4-5 is probably OK. In any event, it would be helpful to state that clearly.

I agree that it hasn't been stated clearly for the teams, but it has been stated clearly for inspectors on the LRI forums.

What was the clear statement give to LRIs? Is turning a corner with a noodle acceptable?

Clearly as legal? or clearly as illegal?

... To assist in applying the fabric covering, fasteners may be used to attach the pool noodles to the wood backing, so long as the cross section in Figure 4-8 is not significantly altered (e.g. tape compressing the pool noodles)

Does this supersede the previous Q&A? It now looks like it is legal to use fasteners (is tape a fastener?)to hold the noodles to the plywood as long as the noodles aren't compressed. They specifically mention "tape compressing noodles".

EDIT: Never mind, I checked and the Q&A has been updated:

Quote:

Q. Is it legal for teams to use tape, shrink wrap, or other soft material to secure the pool noodles to the wood underneath the bumper fabric? In previous years teams have had issues with pool noodles that would sag below the wood.

A. Yes. Please see Team Update 2014-02-11.

Yes, the relevant Q&As have been updated. This is mentioned in the writeup at the beginning of the Team Update 2/11/14:

Quote:

Question 219 in the Q&A asked if Teams could use soft material to secure the pool noodles to the wood during fabrication of the BUMPERS. Since that answer has been posted, we have received feedback from many Lead Robot Inspectors regarding their concern for consistent rulings during Inspections across multiple events. Because of this, we have edited R21-C, D, and E to allow fasteners to be used in this manner so long as the general cross section (Figure 4-8) of the BUMPER is not altered. The answer to Q219 has been updated.

Correct, they have updated the rules to include the actions that teams have been doing for years.

It's acceptable, and in that situation we can expect some amount of compression in the noodles around the corner.

Corners have always been somewhat of a special case. They can't really follow the "general cross section" of the main segment of a bumper. It seems that incidentally compressed noodles wrapping around the corner are in the same basic category as noodles extending straight past the bumper backing and vertical noodle pieces.
