Re: Minibot Rules

I thought this was a good spot to point this out.

There are several rules disallowing certain things on the ROBOT, which in my understanding includes the MINIBOT according to their definition.

R42 implies that you can't use the motor controller to run 2 FTC motors.
R43 & R48 imply you have to use the motor controller to run your minibot's motors

Any thoughts? I doubt this is the case, but I just wanted to point it out.

Does this mean you can't run wire from the battery directly to the motor (bypassing the NXT brick)?

<R42> Each power-regulating device (speed controller or relay module) shall control one and only one electrical load (motor, actuator or compressor).

<R43> Custom circuits shall NOT directly alter the power pathways between the battery, PD Board, speed controllers, relays, motors, or other elements of the robot control system (including the power pathways to other sensors or circuits). 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.

<R48> All electrical loads (motors, actuators, compressors) must be supplied by an approved power regulating device (speed controller, relay module, or Digital Sidecar PWM port) that is controlled by the cRIO-FRC on the ROBOT.
....
D. Each other electrical load (motor or actuator) must be supplied by one and only one approved speed controller, or one and only one relay module.
