Could you let me know if the flags from Turning Point can be reused as legal plastic for competition, as long as we take measures to cover the red/blue/green colors on the flags and use the correct amount? Thanks for your time!
A limited amount of custom plastic is allowed. Robots may use non-shattering plastic from the
following list; polycarbonate (Lexan), acetel monopolymer (Delrin), acetal copolymer (Acetron GP), POM
(acetal), ABS, PEEK, PET, HDPE, LDPE, Nylon (all grades), Polypropylene, FEP; as cut from a single 12” x
24” sheet up to 0.070” thick.
a. Shattering plastic, such as acrylic, is prohibited.
b. Plastic may be mechanically altered by cutting, drilling, bending etc. It cannot be chemically
treated, melted, or cast. Heating polycarbonate to aid in bending is acceptable.
Considering the costs of lexan being so affordable I’d suggest being on the safe side and simply buying new lexan online. The VRC field, on the other hand, could be used for the online challenges this season instead
This seems like an excellent reuse of old game elements that would normally just get discarded. It’s clearly shatter resistant, we’ve been nailing them with balls and running into them with robots all year. There is nothing in this years game that is even close visually, so there should be no issues with vision sensors either.
I had thought that the red and blue colors would be an issue with the vision sensor. However, TT does not have red or blue scoring objects and the mats are large so their signature should be different.
I thought about doing this on our robot, and submitting a recycling award on it.Technically it’s not legal. It meets most criteria, as it is a non-shattering plastic, and has a thickness of 1/16", However, it is not cut from a 12"x24" piece, and even if it said ‘a 12"x24" piece or smaller’, you would still only be able to use a single flag, because it says a single sheet.
The flags are 6"x9.9", so you should be able to use 4, if we followed common sense. I don’t think it would cause you any problems, but it is technically illegal.

That isn’t the intended meaning of the 12" x 24" sheet rule. Read this post for more.
The NBN plastic rules are virtually identical to TT plastic rules, so I’d imagine this holds true. (The only difference is strictly prohibiting acrylic)
