Design and Realization of Pan-tilt Tracking System Based on Stepper Motor

The paper gives a simple and economical solution for constructing a Pan-Tilt tracking system that can be used in camera/antenna tracking object. Based on stepper motor and Arduino microcontroller, the system is actuated and controlled. To get a high efficiency and accurate motion, an optimized speed trajectory is implemented and tested. A graph of motion is plotted to ensure the effectiveness of the method.
