New numbering rules?
 

R2 lays out the new numbering rules, and altough they only added a small section, it is awfully specific:
It's all pretty normal, but the limits on the color of the numbers seems rather picky. Why not specify that the numbers must be of a reasonably high contrast, or easy to read? Perhaps it's becaue i was hoping to be able to do backlit numbers in waterjetted aluminum, but i'm dissapointed by how specific it is.

Re: New numbering rules?
 

The numbers rules likely strict so that there isn't any confusion an what is high-contrast.


Also backlit leds could fail.

Re: New numbering rules?
 

As far as I can tell, it's not illegal to have backlit numbers in waterjetted aluminum, as long as you also have black numbers against a white background.

Re: New numbering rules?
 

Do both. That way when you run out of time to do the waterjet numbers you still are legal. And if by some FIRST Build Miracle you can do both, nobody will see / care about the plain numbers. (Well the inspectors will, but your tumultuous fans won't care.)

I hope all teams follow the new rules, so we can tell which robot belongs to what team.

Identifying robots on the field is one place where creativity and individuality isn't very helpful.

Re: New numbering rules?
 

The issue of contrast could easily be interpreted as part of R2-B, as numbering would have to be easily visible in order to be "unambiguous." And, if done properly, backlit numbers could easily be made visible regardless of if they are actually lit.

I figured this would be the final solution, as im sure my whining will have no influence on upcoming rule revisions :D but I still find it dissappointing, and a little odd that such a specific rule would be placed in an otherwise very flexible game.

It's a big robot. They are small numbers. Having two sets, one in black and white and another in your dancing disco LED lights isn't against the rule.

In prior years, you needed to paint the bumpers. This year, no bumpers but you still need the numbers. Think of the 100's of teams that can't do back-lighted colored numbers. So the min cost effort is black on white that was imposed by FIRST. Think black marker on an index card.

With your resources think of the fund raiser for next year (or maybe this year!!!!) "We'll do your Robot number for $10 per digit per sign!!!!" and away you go.

On the other hand when I look across the 4000 teams building a robot, your team's biggest issue is the back light. I'm humbled that you have solved, designed and are ready to build a robot and have extra, nay, vast amounts of extra energy and build time to move a lighted team number to the top of your build list.

I've added your team to my personal "robots to watch" list, can't wait to see how you make out. :rolleyes:

The color and background restrictions are still a little obnoxious, but no more obnoxious than the restrictions on bumper numbers and infinitely easier to implement. All you need to get compliant is a printer, two sheets of paper, (print two to a page) and some tape, which beats the pants off of any process to get numbers on the bumpers. I've used most of them, from silver sharpies to paint to sewn-on white fabric, and it is VERY hard to get good-looking results.

As for 4901? We'll take the files for our bumper number from last year, flip the colors from white to black, add it to our vinyl stickers with the sponsor logos, and save ourselves at least a couple nights of work. :)

As a graphic designer R2 kills my dreams.

Re: New numbering rules?
 

There are still more than 10,000 square inches of space on your robot to fill with your wonderful graphic design. Just make the numbers so us blind old folks can read them, please?

Re: New numbering rules?
 

I'm thinking black acrylic inlaid in white acrylic would look neat.

Re: New numbering rules?
 

This. I would also suggest the following test:

If you (Edit: or, preferably, your grandparents) cannot read your robot's numbers from 50 yards out (150 ft), give or take a bit, then you may want to reconsider font, size, or stroke. Why 50 yards? That would be some of the farther scouts who are wishing they'd brought binoculars to read your numbers.

Re: New numbering rules?
 

Yeah...But "black light" is really a purple color to the human eye. LOL.

Re: New numbering rules?
 

It is why I have only scouted once...Reading those numbers from way up in the nosebleeds is so very difficult to say the least....And all that data feeds back to the robot team # firstly. (I am nearsighted, I'll run that thread through the needle for you in a flash & read off those tiny numbers on a capacitor or chip without the magnifying glass (but you have to tell me what robot I'm scouting this round, and you better say the number real clearly, then find my golf ball also please). Getting old is hard.:D

Re: New numbering rules?
 

This is one of the times that having a single (or generally low) digit team number comes in handy! My suggestion was to make our entire robot into a giant 4. :p
