We are thinking of doing it qualitatively like for the arms http://wiki.icub.org/wiki/ArmFineCalibration, checking ```yarpmotorgui``` as we move the motor, then replacing the value of the parameter ```Zeros``` in the ```GENERAL``` section of [iCubLisboa01/hardware/motorControl/icub_right_hand.xml](https://github.com/robotology/icub-main/blob/master/app/robots/iCubLisboa01/hardware/motorControl/icub_right_hand.xml), first column. Is this the correct procedure and file? Anything else we should be careful about?
