I am developing a computer vision project which involves developing a system using mirrors for pan and tilt movement of the camera field of view. Mirrors are independent of each other regarding movement. I am confused on which kind of motor should be best suited for rotating the mirrors.
I have already tried stepper motor and digital servo motor for this application with not so good results. With servos control and speed are easy but update frequency is not so good (50 Hz). I am using Pololu Maestro controller to control servos. Since this is comparable to time between two frame capture, motors do start-stop sort of motion which kills smoothness. With stepper motors, control is difficult as compared servos. With no obvious reason to me, when I send commands to stepper motors, it gives very bumpy motion.
I am looking for motors which can be updated almost every 10ms with a resolution of around 0.1 degrees. I also want to control parameters of rotation like speed and angular acceleration.
One similar system is shown on Youtube: https://www.youtube.com/watch?v=vabC62F56q4
