It's no secret that the servos have a potentiometer on the basis of which the servo controls the motor.
Question: are there servos with such a potentiometer already wired to the output. You need to get the position of the actuator at any time.

Any links to buy.

Look for BLDC with position sensors, often used for camera stabilizer
(Have to raise FOC)

Answer 3

These are the so-called intelligent or smart servos, you can also search for the words Serial Bus, that is, servos that can sit on a common bus, they can usually transmit their status.
But this is when it comes to digital position control. For analog control of a conventional model servo, it is enough to remove the cover and solder the wires to the resistor contact, bringing it out.
