Got a kiwi drive? use the PIC to mix your 2 joysticks, and send the desired motor values to the RC, which can still use PID or whatver kind of control you use.

<R69> All equipment connected to the Joystick Ports of the Operator Interface must be powered solely through the power available through the port. External power sources of any type are not permitted on any equipment connected to the Joystick Ports. Portable computing devices may not be connected to Joystick input ports on the Operator Interface.

Interpretations vary, I suppose, but let's take a look at another rule, just a few lines above R69:

<R66> Teams are permitted to connect a portable computing device (Laptop computer, PDAs, etc.) to the RS232 Output of the Dashboard Port of the Operator Interface for the purpose of displaying feedback from the robot while competing in Competition matches. Please note that AC power will not be available at the playing field so these devices will have to run on internal batteries.

So, to me, embedded processor != portable computing device. So long as the power for the PIC comes from the +5V pin on the joystick port, it sounds kosher to me. Am I missing something?
