I am working with a closed loop ARM 3.0, but I am having a hard time understanding how to read the feedback of the position of the actuators with an Arduino. I have read in another discussion in this webpage that some servos, although they are closed loop, they do not provide feedback to the used, just the servo itself. I want to know if that is the case for the Closed Loop ARM 3.0 or if there is a way to read the feedback from the servo itself.
Another solution I thought about is that I could read the signal directly from the sensors located in the joints, but at least for the model I am working with, the cables are not easily detachable.
Thanks for any information on this regard,
Diego.
