You may design and use a custom electronic circuit under the rules that may not have direct control on any function of the robot.
<R57> The use of additional electronics is intended to allow teams to construct custom circuits for their robots.
The custom circuits may be used to indirectly affect the robot outputs by providing enhanced sensor feedback
to the Robot Controller to allow it to more effectively decide how to control the robot. In addition to the
required branch power circuit breaker, smaller value fuses may be incorporated in the custom circuits for
additional protection. All outputs from the custom circuits must be connected to the analog inputs, digital
I/O, TTL Serial Port, or Program Port on the Robot Controller.
