Be careful of your terminology, just because an (RC)servo can be driven to a particular angle, don’t dismiss ‘servo motors’ ...
A motor is a thing that rotates round and round. You can usually control the direction and speed of rotation but you can't position it accurately without some additional equipment , typically an encoder
...because that’s exactly what’s inside an RC servo!
It’s that extra glue that makes a very important distinction.
Thanks for making me clarify that point!
