Bumper Rules

[kwam dawg]

The rules state that you must have 8 inches on the corners of the bumpers. what if one face of our frame is under the 8 inches (being 6 inches wide)? is it ok to cover all 6 inches or do i have to extend the face of the frame to 8 inches to meet the bumper requirement

Can you show a picture of what you are talking about. If i remember correctly the rules state that it has to be at least 8 inches long.

Actually, if there are at least another 2" of bumper around the corners of the face, then it is legal, as per Figure 2013-01-15 (http://frc-manual.usfirst.org/Updates/0#term 37)

Edit2: Removed picture, it was too big.

Another bumper question:

Does anyone know what the protocol on R27 (fill all corners with pool noodle) is when the bumper segments on either edge of a given corner are at different heights? On the one hand I feel sort of wrong not putting noodle all the way up vertical edge wherever either bumper borders, but on the other this seems to violate the cross-section dictated by Fig 4-4 and enforced by Q42 (https://frc-qa.usfirst.org/Question/42/questionlink).

I can ask the Q&A, but I wanted to make sure I wasn't missing something obvious. In prior years--didn't some teams basically put a diagonal on one edge to join the two heights? Is that legal this year? I tried to re-ask this parallel to the ground question in Q187 (https://frc-qa.usfirst.org/Question/187/must-the-through-axis-of-each-individual-bumper-segment-be-parallel-to-the-ground-or-may-it-be-tilted-provided-it-is-fully-within-the-bumper-zone-and-meets-all-construction-frame-dimensions-and-rigi), but it may have come out wrong.

In this case, no. You don't have 8" on each side of the vertex.

If you were to build an 8" bumper on the existing frame design, you'd run afoul of R29-A; looks like you'll need to add about 2" of structure to support the bumper.
