What causes servo "jitter" and how can I cure it?
February 2, 2011
Edit Sorry, should have read this first.
Not sure I'll be able to implement fritsl's solution, though.
I have a humanoid robot, which has 16 original servos, plus I have added 2 standard servos in claws, and recently 2 more micro servos for the head.
These 2 micro servos occasionally get a bad case of the "jitters", not all the time, but intermittently.
As soon as I touch the head, the jittering stops.
Can someone explain to me what possibly could be the cause, and how I could maybe cure it, please?
(I should say that the servos themselves do not appear to be faulty, as they work fine off the robot.)
