The numbers pass all the requirements specified in R29 (width and stroke) and they are white. My concern is the sparkle in the white. Would this still pass inspection? I haven’t put them on yet but I want to make sure this would be okay before put it onto the fabric.
What material is it? It’s hard to tell from the picture, but I think it generally looks OK. My only concern would be the “sparkles” coming off on other people’s robots, the field, etc. But I can’t really tell if that would be an issue without looking at it in person.
A fair warning at this point in the season - if you’re adding these to existing bumpers, disassemble the bumpers before ironing them on. I had a team this season that assembled their bumpers first, and then ironed on their numbers. The heat from the iron melted the pool noodles, removing about 1/2 their width. That was a problem, and something that you would then have to fix at champs on Wednesday before passing inspection!
The material is “iron on transfer paper” according to the store’s website. I’ve been carrying the numbers around and the sparkles haven’t come off so I don’t think that would be an issue.
I’ve already stripped the old bumpers of the old fabric. I’ve heard stories like that of teams ironing numbers on once the fabric is assembled and it doesn’t sound fun. I have brand new stitched fabric that is ready to have the numbers ironed on. Once they’re on then I will put them on the frame.
Ok…ok…now I HAVE to ask. I almost bought glow in the dark white instead this year. Realized my mistake just before I paid and got the regular one instead. But a few kids were disappointed when I told them. I was afraid they might not be legal. (Even though you really can’t tell the difference by looking) The kids just thought it would be fun when they put it in the trailer and the numbers glowed. So does this mean they would be legal?
There’s nothing in the robot rules prohibiting the use of glow-in-the-dark material. So long as in the state normally experienced at events (and inspection) they appear white and in compliance with the rules I can’t think of any reason to prohibit them.
Think about it another way; from the inspector’s perspective is there anything about the material that would fail to pass inspection if they didn’t glow in the dark? I can’t think of anything.
