Uarm Servo motors

Can I use simple servo motors (like MG996R) without analog feedback to control uarm?

the simple answer is no. when you first power up your uarm you need to do a calibration. that basically finds the limits of the arm using the feedback. one way you can get around that is to solder a wire onto the center pin on the feedback pot inside any servo and use that. or manually program the srduino with your own code to not use feedback. without feedback you dont know where the are is.

Thx for the reply

Should it work?

Yup. Ramble ramble this post has to be at least a certain length
