One of the large servos won't zero.

I found that one of the large servos I received won't zero properly.
When power is applied it goes all the way to the stops (CCW).
I have tried switching pins on the servo control board and the problem is unique to this syncro.
Rapiro won't walk or turn correctly with the defective syncro.
I understand the servos are unique to Rapiro. I don't know if they are repairable.
If anyone can share some light on the problem it would be much appreciated.

Did it not work from the first?

We are preparing to launch the RAPIRO webstore.
We are going to sell servos separately in near future.

I have the same problem, it's the left foot pitch.
I zero him but few second later it begin to move randomly!
My power supply is AC 12V 5A and I try li-po 7.4V 6000mAh!
Pls tell me when you sell servomotor in the web store! ++

I received a replacement servo motor and Rapiro works now.
I made an web/python/cgi program that will send the the basic commands in the sample sketch.
I am looking forward to instructions on how to make the Rapiro do neat things like make coffee and sweep the floor as shown in the videos.
