Hello,
I have successfully gone through the tutorials and manual to set up JD Humanoid. He can do various actions, songs etc , even do the facial recognition. However, I am noticing that there is a persistent "clicking" or "humming" sound coming from the EZ-B controller, sounds almost like a servo in action. Is this normal? Being afraid that I may burn a motor out, I am not running JD for more than a few minutes at a time. I have gone through the tutorial to Fine Tune JD's servos and his posture seems to be perfect. Appreciate if someone can confirm if this is normal or I need to look into the controller and if so, where can I find information to troubleshoot sound coming from the controller?
Thanks
Does the speaker work for audio - like the demo dance?
If the sound is truly louder than normal you can always open the EZ-B enclosure with a No.1 Phillips screwdriver and look to see if maybe a magnet in the enclosure has come loose. A magnet attached to the underside of the EZ-B main board can increase the noise you are hearing.
