When Ryan Hall gets sniped

4

Starting Configuration - No parts may extend beyond the vertical projection of the BUMPER ZONE. <R02>

This item on the inspection checklist should say FRAME PERIMETER instead of BUMPER ZONE.

5

No everything needs to be inside of the BUMPER ZONE at the start of a match.

Err… Never mind me I read that wrong.

6

The bumper zone is a zone 0-7 inches from the floor. It should say FRAME PERIMETER.

R02. In the STARTING CONFIGURATION (the physical configuration in which a ROBOT starts a
MATCH), no part of the ROBOT shall extend outside the vertical projection of the FRAME
PERIMETER, with the exception of its BUMPERS and minor protrusions such as bolt heads,
fastener ends, rivets, etc.

Nothing can extend past the maximum configuration allowed for the game this season in teleop.
However, everything has to be inside the vertical projection of the frame perimeter at the start of the match…whatever that may be depending on each team’s robot.
The only major difference here vs. previous years is that the bumpers are included in the maximum configuration dimensions.

Team Update 11: Oops.

So they explicitly call out R34-B when it comes to relays now:

So other relays would count as custom circuits and the only relays that are actually allowed to control motors are no longer manufactured…

FRC has the best rules folks… simply the best.

Awkward. Just awkward.

It may also be a good idea to correct this language:

No bumper segment may be unsupported by frame perimeter for a length greater than 8”. Gaps may be ≤ ¼” deep. <R31>

That makes it sound like you can never have any unsupported bumper segment longer than 8", AND you can never have gaps > ¼” deep. The actual rule is an “OR” of those two conditions:

R31…Additionally, any gap between the backing material and the frame:
A. must not be greater than ¼ in. (~6 mm) deep, or
B. not more than 8 in. (~20 cm) wide

So you can have unsupported bumper lengths > 8" as long as the gap depth is ≤ ¼”. Conversely you can have gap depths > ¼” as long as the unsupported length is ≤ 8". The drawing shows this as well.
