<R13f> clarifies that small power internal power sources are permitted for powering nonfunctional decorations:
f. Internal power sources (e.g. for a small blinking light) are permitted, provided that no other rules are violated and this source only provides power to the non-functional decoration (e.g. does not directly or indirectly influence any functional portions of the Robot).
Additionally, past rulings (#698) have stated teams are permitted to power and control light strips via an externally accessible port on the V5, provided that teams do not violate <R13g> or other robot rules in the process.
g. Decorations which provide feedback to the Robot (e.g. by influencing legal sensors) or to Drive Team Members (e.g. status indicators) would be considered “functional” and are not permitted.
Some LED Light Strips additionally have a wireless IR receiver (built in) and remote which allows them to be remotely controlled (switching colors, blink configurations, etc.).
Are these light strips legal? Would it be legal to change these light strips during a Match?
