Hi all.  The movements have been finalized on the head bobbing mech.  Click MORE below to see the new video.   Spawn says that the running a script on the servos using the "servo" service makes the servos jitter during movement unless you use the -1 speed setting. Due to the weight of the skull (which will be added soon), he didnt want to burn out his servos using that speed setting.  Here is a look at the full movments before the rest of the skull is attached.   Any suggestions on fixing the servo jitter would be appreciated

Whenever I hear "jitter"  I think :

  • more power - make sure electronics nor motors are starved
  • seperate motor power from electronics - (keep the signal clean)
  • put a couple caps on your grounds - filtering caps are a good thing

Great progress! Interesting head movement!!

Jittering servo is often related to poor power source ( too low Amps).

When you exceed more than 3 to 4 servo on a breedboard, the servos can start to jitter because the breedboard can not supply enough Amps flow through it's connections.
