I have assembled my JD Humanoid Robot. When I connect to him, one of the servos makes a buzzing sound and won't stop unless I turn it off. For instance, the servo was the upper part of the left leg. When I connect, it lifts the left leg all the way and buzzes. I then switched the servo to an arm, and when I connect, the servo bends the arm fully and buzzes. I am not sure what I need to do to fix the problem.
If so, servos will buzz when they hold position/weight.
its 1 to 90 degree to 180
90 degree is center
Occasionally, servo calibration will be off due to alignment of electrical and mechanical components during manufacturing. This means adjusting the one mis-aligned servo with a philips head screwdriver.
You're almost there
I will attempt the calibration procedure.
Thank you for the video - it corresponds to my previous suggestion that the servo requires calibration. In fact, you can simply remove the screw and align the servo without requiring to take the robot apart. Here's a sketch of what i mean (instructions below)...
1) Remove the screw
2) separate the bracket from the servo
3) connect to the robot so it moves into initialization position
4) place the servo back in the bracket aligned as demonstrated in the sketch above
5) replace screw and tighten
6) You're off to the races
PS, i have updated the JD assembly instruction to identify this step for future users. Thanks!
