Twitching Servo

Skip to comments   Jump to end

Heya,

Today I played around with my robot, and one of the servos started "twitching", and I mean really twitching. It responds when I change its position, but it wont hold it and starts going crazy instead twitching back and forth.

I've tried different ports on the EZ-B so I know it's the servo.

Is there anything I can do about it, or is the servo broken?

Thanks:)

I had that too. It feels like the servo is damaged, however it is still working. When I limit the minimum and maximum value between 20 and 80 it doesn't happen. This is for my servo with ultrasonic detector more than enough to sweep it's environment in front of the robot.
