Static / dynamical friction parameters of XM430-W350 servos?

Hi,

I’m currently building a bipedal robot based around the Dynamixel XM430-W350-T (used in OP3 humanoid). The aim of this project is to test a sim-2-real walking policy.

To do so, we need physical parameters to constraint the data augmentation procedure.

My question is the following : Is there any ressource or people that have identified the friction coefficient (static and dynamical) of the XM430-W350 ?

Best regards,

Quentin.
