Beaglebone AI-64 Water Gun Sentry Turret

For our project, we created a water gun sentry turret. This project consists of several components including the BeagleBone AI-64, a stepper motor and driver, a servo motor, a water pump, and a relay to fire the water pump. In addition, this project runs a Machine Learning program on the BeagleBone AI-64 to detect if a face is in view of the connected webcam and if the face's mouth is open.

When the camera detects an open mouth, the centroid of the mouth is calculated and the servo adjusts the water gun's angle in order to shoot water into the mouth. The water shot is pumped from a water reservoir using the water pump which activates soon after the mouth is detected to be open.

Below are various images of our project that show the enclosure for our circuitry as well as the circuit itself.
