3. Project Overview
Design of a turret with an armature structure that holds an Airsoft gun
Detect and fire at enemies through both motion and threshold detection
Gun will pan/tilt based off coordinates translated by the microcontroller from the video feed
Friendlies can disarm the weapon with a remote

10. Project Demonstration
1. An ability to electronically fire an airsoft pistol (either autonomously or manually).
2. An ability to detect off-camera motion via ancillary sensors.
3. An ability to remotely disable device to prevent “friendly fire.”
4. An ability to automatically detect a (hostile) target within the camera’s field of vision.
5. An ability to pan and tilt the firearm assembly (a minimum of) 45° in the longitudinal direction and 30° in the latitudinal direction.
