I don't want to dissuade anyone from anything, but I'd like to draw attention to R58 from last year:
Quote:
If a motor or servo is controlled via the MXP, it (or its power regulating device) must be connected by one of the following
methods:
A. directly to any PWM pins,
B. via a network of PASSIVE CONDUCTORS used to extend the PWM pins, or
C. via one approved ACTIVE DEVICE:
a. Kauai Labs navX MXP
b. RCAL MXP Daughterboard
c. Rev Robotics RIOduino

I can find precious little other information on ACTIVE DEVICES with a quick search, but I seem to recall that they were prohibited last year except for the 3 above (though the wording of that rule seems to indicate that was only if motors were connected through it)
I'd tread carefully on investing significant amount of time/money into this before we know the rules for this year, and what will be allowed to connect to the MXP.
