I am looking for an alternative to the servos with the pots removed on the InMoov robot. I was wondering if a continuous servo could replace these considering the comprehensive control we now have using ARC. I have removed a few of these pots but am still having issues with the shoulders operating reliably. I cant help but think there must be a simpler solution to this. Any advice welcome.
Pots are always required, no matter what. They report the position of the output shaft to know when to stop moving the motor.

Soo.....what about a continuous rotation servo? Sorry probably not very clear, I'm looking for an alternative to removing the pots from the servos and mounting them externally...
No - pots are always necessary to report the position of the output shaft of a servo. Without a pot, the motor would not know when to stop turning. You can find out more how a servo works (including continuous rotation) here: https://synthiam.com/Tutorials/Lesson/48?courseId=6
As you will read from that important tutorial relevant to this discussion, a continuous rotation servo does not know its position and spins like a regular motor (i.e. Ceiling fan). If you use w continuous rotation servo for your robot, the joins will spin in circles like a helicopter.
Thanks for your reply DJ, i am currently looking into the possibility of using degree wheels and sensors (like the ones in your photocopier) and similar to a crank angle sensor on a car, simple and accurate. Appreciate your help.
