Non-functional = No broadcasting video to drivers to give them a "functional" advantage of an improved view on the far side of the rack.
This rule has been around for several years. While teams can't broadcast video direct to their operator stations, if approved, teams have had wireless camera feeds shown on the big viewscreen during matches (48 did this a few times in 2004) or have recorded the feed in their pits for future use.
8.3.11 Non-Functional Decoration Rules
Teams may add “non-functional” decorations to ROBOTS under the following conditions:
<R107> Decorations must be on the ROBOT at the time of final inspection, and must not cause the
ROBOT weight or size to exceed the limits specified in Rule <R07>.
<R108> Decorations must not affect the outcome of the match, and must be in the spirit of “Gracious
Professionalism.”
<R109> Any decorations that involve broadcasting a signal to/from the ROBOT, such as remote
cameras, must be cleared with FIRST Engineering prior to the event and tested for
communications interference at the venue. This is the one permissible exception to Rule
<R66>. Note that 900 MHz camera systems will not be approved, and are not permitted at
any time.
<R110>
Decorations may draw power from the 12v electrical system as long as they are powered
via a dedicated 20A or 30A circuit breaker and do not affect the operation of other control
system components.
