Hi,

Servo 12 was about 13 units out.

Servo 13 was about 5 units out.

Not a massive amout of difference, but enough to stop it walking. Seem to happen all at once which makes me suspect it may have had a knock on one leg.

Thanks

You're probably right. That's not much of a shift, and could have been caused by a fall or sudden impact.

Hi, during the football session a few weeks back, the Manoi suddenly started to fall over after every step.

Couldn't get him to walk at all. Finally I have managed to get a little quality time with him and had a look for broken servos, loose brackets, hairline cracks, etc but found nothing.

I adjusted the home settings on H2H to bring it back to normal and its now working fine again. two servos needed a fairly major adjustment.

Has anyone seen slipping on the servos before, or is there some way that a power surge could have afected the ICS parameters somehow?

Thanks


Do you recall which servos needed the adjustment, and how much they were off?
