Robonova emits a high pitched whine

[Rosco]

Hi All,

I am hoping that this is a noob question.
Built my Robonova and got it to standup on first power on but it emits this high pitched whine which is most anoying.

Investigated and found that it is comming from the servo's when they are under static load.
During movement no noise.
During no movement and no stress no noise.
During no movement but placing some load (as in standing holding the torso in position) they scream.

Help please, is this normal.

Hi Rosco, I´m a noob like you, but my RN-1 emits pitched when the servos is under stress, but is a little pitch, like the sound before a bomb

Yes, this is normal.

This is the sound of 16 servos awaiting your command..

(When doing the zero settings - page 64 in the manual) I can tune out the high pitch sound in my Robonova servos by recalibrating the zero point using the RoboBasic software. Generally it only requires the difference of one point to go from sound to no sound. Hope this helps.

Many thanks for the above , I managed as mentioned to turn down the high pitched whine by recalibrating the zero point.

it's the servos under strain(not bad) and once you zero it it just get a lot quieter and higher pitch, the noice will come back if for exapmle the hips are puchsing against each other.
I strongly recomend zeroing, i foung that to make it remember the zero you have to open up a program, the template program and write the zero poistions into a program
