Hi @AntonioConsilvio

This PR fix the value of the joint 0 (pitch) of both legs from 100 to 150.

It's the first time that I see a gear ratio = 150:1. Our HD sizes for these joints are generally 100:1 or 160:1. Can you please confirm?

Ok clear now: the hip pitch has a further 1.5 ratio due to the cable transmission.

Thanks @fiorisi 👍🏻

I've also checked that e.g. iCubGenova11 has the same ratios.
