@Rongzhong Li feedback mean 3d sensor ?

Thank you very much, you have new email in your mailbox :)

Is the Ankle making walking any better or it is mainly design feature ?

I did all points to be sure. Nybble is now working but it have "neural tick" at some point, for example when i press "ch-" to sit then at some point - always at same, all or almost all servos shake for a tenth of second then return back to correct track. It happen even when i hold it in air so i guess it is not servro load ?

Ok problem solved with resoldering all critical looking points :)
