I have several questions about the motors composing the head:
First, I did not find the documentation of these motors on the Reachy 2021 documentation web page. You mention a link to the documentation of the motors composing the arms but I did not find something similar for the motors composing the head. The only thing that I found is that these are DC Maxon motors, but that does not help much. Please correct me if I am mistaken, otherwise could you please make this documentation available ?
Second, what is the maximum speed of the motors composing the head ?
Third, on your documentation, you show examples of the turn off smoothly method. You use this method for the arms but not for the head. I suspect that the motors composing the head don’t allow to control their torque and thus don’t allow to implement the turn off smoothly method for the head. Am I right ?
