If the robot is running and the only thing changing is the camera working and not working it sounds like an intermittent connection. In our case the tilt servo would stop working intermittently so it was obvious which wiring to check. We found it (we thought) by tapping on the various connectors. We cut out the bad connector and just soldered the wires together. But then tapping on the new connection still caused intermittent problems so the wire obviously had an internal break.

When going from normal operation to disable the PWM outputs get turned off so the camera servos should simply stop. If that's not happening I don't know what might be going on. We tested and found our camera servos could not be driven to full throw without causing binding which makes the servos buzz.

During programming, power on, or anything which changed modes, we would get a single servo movement which is typical of when a PWM signal is turned off and on.

So what do you guys think? Is it a wiring issue? Code? or something else? Ill try to provide whatever answers and data i can if asked. Thanks for your help!

Was your camera "not working" simply the servos would stop moving or was it the camera data would stop working (shown on the terminal)?
