Bumper zone height

I must be missing something, but I can't seem to find the height of the Bumper Zone anywhere in this year's manual. Am I? Or should I post this in the Q&A?

Thats what I thought... because if someone as it at the 2 in mark and someone else has the 10 in mark then the 2 bumpers wont even contact :/

2+5 = 7. 10-5 = 5. 7-5 = 2" of overlap.

So yeah. They will.

Re: Bumper zone height

I noticed that only the frame vertices need to be protected this year. Bumpers do not need to be continuous, apparently.

They probably did this to allow for floor pickup. Most teams probably will still have the bumpers for the full length if they don't have a mechanism on that side, though.

Re: Bumper zone height

They may have also did this to allow teams to climb over the center rail.

Re: Bumper zone height

DO the bumpers need to be level with each other?

No, they only need to be within the bumper zone, as per [R29].

so bumper zone is within 2 to 10 in off the ground then and around exterior corners.

Re: Bumper zone height

To throw in what I believe to be a new bumper rule,

Quote:

R35: The numerals must be at least 4 in. high, at least ¾ in. in stroke width, and be either white in color or outlined in white.

Emphasis mine.

The 148 numeration method of stenciling in with a silver sharpie is obsolete I guess, unless you're able to make a white sharpie show up. Bumm(p)er.

Thomas,
Not really a new rule, just more distinct. 'Contrasting' under some lighting conditions was not 'contrasting' under others.

Re: Bumper zone height

I didn't want to create a new thread, and my question is similar:

Sorry for the large size, not sure how to make it smaller.
My question is:
Did FIRST make a mistake/typo in this picture? The two gaps labeled 10 inches are clearly not of identical lengths ( i even measured to make sure :P). I understand why the "not ok" on the left is not ok, but, given the current numbers, i do not understand why the "ok" on the right is ok.
Thanks!
