As agreed with @S-Dafarra, tomorrow early morning, November 5th, would be great to get the attempt to fix the issue

@Uboldi80 @gsisinna @GiacomoVassallo13 I think you already did some fixes, but it is still necessary to unmount the mechanism. Am I correct?

Buongiorno, la testa di iCub 3 è stata staccata e il collo sottoposto a manutenzione. Per quanto riguarda il gioco sul giunto dello yaw, si è risolto aggiungedo un rasamento trovato magazzino cod 6287, per tenere fermo nella sede il cuscinetto. drutff

Purtroppo è stata riscontrata un anomalia grave tra l assieme RC_IIT_010_A_004. Il componente RC_IIT_010_P_024 (giallo) risulta storto una volta montato sul pezzo RC_IIT_010_P_008 (grigio). Immagini della posizione corretta presa a CAD.
