Objective: This device shoots a laser at the face of a person standing in front of it. This laser ray moves with the person as a real-time tracking device. This project was a prototype to show that we could manufacture and implement this technology in various settings. The most common of these would be industrial sorting (apples, rice grains, etc.) and military tracking applications.

Approach: I used a Raspberry Pi3  microprocessor with a pi camera v2 to detect the human face and calculate the face's X-Y coordinates. Then two PM35L stepper motors are used for the YAW and PITCH axis movement of the laser light beam.
