There is something I need to say here. Actually two things.

1) Last year's rules do not apply to this year.
2) It might be a good idea to ready the blue box following [R08], particularly line D. Lasers are legal if they're Class 1, or completely enclosed in a COTS part.

That said, an IR emitter would be counted as a custom circuit, and subjected to custom circuit rules as well as general robot rules. I would probably figure that it is legal, because I can't find anything saying it isn't.
