Re: Backup Battery life and the CMUCam

I also wondered about this... R63 would seem to indicate that a 6V regulator is an acceptable "Custom Circuit" as long as it it not connected to an output device. To me, this would make the CMUCam OK, but not a Servo. Hmmm..

My reasonning... Since a Servo contains a motor, and is covered by various motor limitations rules, and R63 says that a custom circuit cannot power a motor directly.... so........ wouldn't it be excluded?

Phil,
NiMH batteries are not allowed due to their unusual reaction when exposed to air. Regulators on custom circuits are allowed but they may not be used to power servos or other motors on the robot. They may (as interpretted in the past) supply power to sensors used in conjunction with the custom circuit. All control initiated by the custom circuit must be passed through the RC to control motors, lights, servos, pump, etc.
