R08

A. Shields, curtains, or any other devices or materials designed or used to obstruct
or limit the vision of any drivers and/or coaches and/or interfere with their ability to
safely control their Robot
B. Speakers, sirens, air horns, or other audio devices that generate sound at a level
sufficient to be a distraction
C. Any devices or decorations specifically intended to jam or interfere with the
remote sensing capabilities of another Robot, including vision systems, acoustic
range finders, sonars, infra-red proximity detectors, etc.(e.g. including imagery on
your Robot that, to a reasonably astute observer, mimics the Vision Target)
D. Exposed lasers other than Class I.

So it is legal when it doesn't violate any of these rules. This will be determined by inspectors or refs on the field.
