Bumper Number

Can We have twice the team number written on the same side of the robot?

I sure hope so.. we didn't intend to do so, but marked out too many places for the screen printer to print numbers -- we only asked for 8 4digit numbers to be printed, by they printed 12 of them since they were marked out on both of the short sides of the U shaped bumpers.

Reading the rules, I could not find any rule that prohibits it.

Team numbers must be displayed on the BUMPERS and meet the following criteria:
A. consist of numerals at least 4 in. high, at least ½ in. in stroke width, and be either white in color or outlined in
white
B. may not wrap around a corner of the FRAME PERIMETER
C. be positioned around the ROBOT such that an observer walking around the perimeter of the ROBOT can
unambiguously tell the Team’s number from any point of view.

So I guess multiple numbers are OK if they meet the part about "unambiguously", to be determined by your inspector.

That happened to us last year. At the Long Beach Regional, they told us to change it. We quickly stapled some bumper fabric over the extra numbers and they let us go. Maybe they will be a bit more lenient this year.

This year's rules != last year's rules.

Are you sure? I don't know why people are building their robots so small this year. Last year they were all 38"x28" so that's what we did this year

My internet sarcasm senses are tingling.

So, does that mean that a round robot (which is considered as having an infinite number of corners) can't have legal bumper numbers ?

Use common sense instead of legal definitions. If you have your numbers about every 90° on around robot you should be fine.

They even have C) written in a way that doesn't specify you need it on every side, Just in a way you can see them from any view. The wording is quite different from past years, and totally answers what you would do in the case of a circle.

DonRotolo used COMMON SENSE.

Circles have zero corners, not an infinite amount, so if your robot was perfectly circular, then technically you wouldn't need bumpers at all. I imagine you'd be asked to put some on anyways, though.

To clarify, do you have:

a) two sets of numbers painted/ironed-on one side of the bumper, or
b) one decorative number on your robot (e.g., sticker on Lexan) in addition to a painted/ironed-on number on the bumper?

option a)

Andy,
I believe the GDC has defined a circular frame as having an infinite number of corners and as such needs to have bumpers all the way around.
