If you're using it to line up at startup, I'm not sure.
As for having a pointer on your robot during a match to help align, it should be fine.
Why? Because we did it last year.
Last year we mouned a class 2 laser from radioshack in the center of our bin grabber. It was used to align to the center of a bin. Made it easier for the drivers to see were they were facing. It was a class such that it would not cause eye damage.
It passed inspection, and yes, they did question it, but when our motives were explained, it passed.
Now, we didn't even use it cept for maybe once since we dismantled our stakcer, but I just thought I'd ought to say that there indeed has been an occurence of this passing inspection.
And It didn't directly effect the outcome of the match at all. It simply helped the drivers align with objects on the field.
