Post Continuous Rotation Servo Problem
My team has recently been having some problems with the continuous rotation servo. Whenever we hook it up, it is constantly turning very slowly, even when no programs are running. There seems to be no way to get it to stop, other than killing power.

Anybody see a problem like this before?

Hi FTCTeam,

Which rotational servo are you using and have you tried a different servo? This is unfortunately quite common for cheap rotational servos. Some better ones will have a small screw or dial which can be adjusted to eliminate travel and noise.

If all of your servos are behaving the same (same direction of rotation, same speed) then this may be a ROBOTC issue. Otherwise it may be that the servo's "deadband" is off, which as I've said, is unfortunately all too common among inexpensive rotation servos.

We had this problem once. We fixed it by finding a value at which the servo stops. Try plugging in values that tell the servo to go the opposite way that it slowly turns at "zero".
