True? False? Is this concept a violaiton of the rules, in spirit or otherwise?
The concept that a second controller could handle the computation is legal. However, that is the extent of its involvement. The input to any Spike or Victor must come from the IFI Robot Controller.

Forgive me if I sound dense, but we're newbies, so be kind.

By the Spike and Victor, what are you refering to? The second conroller we are thinking about would be used solely to keep the the CMUcam on track with the "green light" and, subsequetly, aim our firing mechanism toward the target.

Is this legal, and am I a making sense?

Thanks.

You are making perfect sense. The only problem is that your second controller can not directly aim your firing mechanism. As Mr.Skierkiewicz said above, "You can only have one RC on the robot and it must be the only controller that directly affects motors, valves, servos." That means the second controller would have to tell the IFI Robot Controller to aim your firing mechanism.

Custom high impedance voltage monitoring or low impedance current monitoring circuitry connected to
the robot’s electrical system is acceptable, because the effect on the robot outputs should be
inconsequential.
• Directly affect any output devices on the robot, such as by providing power directly to a motor, supplying
a PWM signal to a speed controller or supplying a control signal to a relay module
• Be used for wireless communication, such as sending or receiving a signal to and/or from the alliance
station
• Connect to the radio or tether ports on the Robot Controller
If you're wondering why this is... at the competition FIRST needs the ability to disable all moving parts on your robot without your team's assistance. By wiring all of your outputs from the IFI Robot Controller they are able to do this.

EDIT: As many people have noted, robot controllers are not on the additional parts lists. Therfore, they would need to come out of your budget. The rule below would not allow for you to use a second IFI Robot Controller. However, if you were using a different controller under $200, than it would be perfectly legal.

A "Victor" is a speed controller . A "Spike" is a spike relay.

You'll see that a lot around here.
