Bumpers again...

[Hiromi]

Ok, so the dimensions for the standard bumpers are 38x28, right?
If we trim it down to 36x26, would they no longer be considered standard bumpers?

[Zoheb N]

They would still be considered standard because the rules only say the following


STANDARD BUMPERS – Bumper assemblies designed to attach to the exterior of the ROBOT within
the BUMPER ZONE, and constructed as specified in Rule <R37>. STANDARD BUMPERS may weigh
up to 15 pounds, and are excluded from the weight and volume calculations specified in Rule <R07>.

[ALIBI]

The minimum length of a section of bumper is limited to no less than six inches. Having a pair at 26 inches is perfectly legal.

if the minimum length of standard bumpers is 6 inches. what is the minimum width?

The wood backing that makes up the standard bumper must be:

This (5 in.) is the width of two pool noodles.

Add in the thickness of the 2 pieces of aluminum angles used to clamp the cloth onto the plywood, and you'll get the height of the standard bumper.

Do bumpers count in the 72 x 72 (<R12>) rule?

The bumpers are included as part of the robot, and must fit in the 72 x 72 virtual box, this question has been answered in the Q&A

I read the Q&A but, I'm still a bit confused. So, you're saying that it is completely unlike last year, where when we weighed in and measured up, we took the bumpers off. This year they have to stay on, correct?

[MrForbes]

When the inspectors measure the robot to fit in the 28" x 38" box, the bumpers are off.

When the robot is on the field, the virtual 72" x 72" box surrounds the complete robot, with bumpers, and the robot is not supposed to go outside the virtual box.

Last year there was a smaller size limit, 60" x 60", to which the robot could expand at the start of the game.

Nothing has changed....except the size of the virtual box is larger, by one foot in each direction.

Oh, okay.
That makes sense now!
Thanks, Jim... err... Squirrel..... err....Mr. Forbes!
