I have a problem to position the turret of my robot. I use a continuous 360 servo. I would like to position the servo for an angle between 0 and 180 degree. The goal is to have a kind of radar to detect the obstacle. So the turret should go on the left and on the right continuously.
At the beginning with a 360 servo, I get the good positions for my servo but after some time it is become difficult to know exactly the position of the servo.
So I plan to buy and use a servo with a limit angle to 180. But I would like to know if I will get the same problem? How I will know the position after many movement of the turret? Do you think I will lose some precision?
