But, if they are being controlled by an Arduino Micro (Which seems to also be legal, <R11>.D.ii) Can they technically be considered "Non ROBOT controlled, thus allowing for an independent 9V battery? This is what we interpreted. Any thoughts?

We powered an led light strip via the main robot battery pack, running
it through a 7805 voltage regulator (with a huge heat sink) last year.

We had a schematic of the voltage regulation circuit and a fully educated
team member for judging should a judge question the setup.

Note that all microcontrollers, which includes an arduino, must be
powered from the superpro protoboard, and it can only supply
something along the lines of 8mA. A stock arduino will draw 20mA,
so we ran a barebones ATmega328 to drive the led strip.
