            let me know about your caps result. I had an issue with a digital servo impacting another analog one. After connecting the dig servo to another power distribution point the problem resolved itself but having a cap for the signal lines looks to me like a more robust solution

      Update: Actually had a problem with left shoulder rotation servo (continuing small repositiong with growl) and after a while it stopped to move (fuse and servo rather hot) so the fuse did it’s job.
      Have added now the 104 (100nF) caps for all shoulder servos (between signal and ground) and as it did not completely stop the growl a lot of has gone…[Read more]

    Yes, I hacked a flexihand and put the servos for the fingers in the palm of the hand and added a servo for the additional wrist movement. I have also just finished adding flexible joints to the original InMoov hand and it works pretty good and can hold objects fairly well. I posted a couple of videos on Youtube about the flexihand.
