Bumpers

[Hellfeier675]

We just looked up the past rules and they are written exactly the same.

BUMPERS must protect a minimum of 2/3 of the BUMPER PERIMETER. Teams are
encouraged to maximize the area of the ROBOT protected by BUMPERS. But up to 1/3 of
the BUMPER PERIMETER may be unprotected to provide flexibility in design options.

That was the difference in past years.

The 2010 rule is the same, because it required bumpers around 100% of the robot.

The 2009 rule has this very notable difference:

Contrast this with the 2011 and 2010 manuals, which say 100% coverage multiple times.

Hellfeier675, accept what these seasoned veterans are saying. They know the rules front and back, you have demonstrated that you clearly do not. Take this as a learning experience and move on. We want you to pass inspection just as much as you do.

I'll bring extra bumper material to the Davis Regional for when you don't pass inspection with your current bumpers. See you in 8 days!

Thank you for your concerns Mr. Corsetto, but team 675 has a solution. Everything is working well, and we are 150% sure that we will pass inspection. Your offering of bumper matieral will not be needed. have a nice few days.

Yes I asked this on the FIRST forum and we found the little hidden rule that we seemed to have skipped over. We have fixed our robot quickly and effectively and won't be needing your bumper material. Coming from our veteran team we saw the rules that we observed as one way and were wondering if there was something we were missing. We weren't trying to tell everyone else that they were wrong, we just wanted to find out if we were right. Now, we accommodated for these bumpers just in case we needed to and from the looks of all the kind help from delphi, it seems that we had to add those bumpers in.

We'll see you in a few when we get to sac. Good luck...

Glad you guys were able to come up with a quick fix. Good luck at the regional.

Sorry, but the rules this year are different in some areas from all previous years. You may not have gaps in the bumper coverage. The Figures 4-2 & 4-3 in R07 are very clear. If you are competing this weekend, I would hope you are working on an alternate plan for your robot design and function. There is one thing that is similar to past years and that is your robot bumper design must satisfy all of R07, not some of the paragraphs.

A. BUMPERS must provide complete protection of the entire FRAME PERIMETER of the
ROBOT (i.e. BUMPERS must wrap entirely around the ROBOT). As part of the 100%
coverage, BUMPERS must protect all exterior corners of the FRAME PERIMETER. For
adequate protection, a full segment of BUMPER must be placed on each side of the corner
(see Figure 3-2).

[TEE]

From the rules, it was my understanding that the frame perimeter by definition is convex, and so the bumpers have to be convex, correct?
