This project involves developing a real-time automated target object tracking system. The system uses image processing algorithms on a computer to recognize and track a moving object. A microcontroller communicates serially with the computer to control motors and a laser gun. When an object is detected, the camera rotates on a stepper motor to maintain view of the target. A laser gun mounted on servo motors also tracks the target under control of the microcontroller. The system has been tested and the communication, stepper motor control, and servo motor control are all functioning as intended.
