How to Make a Raspberry Pi Motion Tracking Airsoft / Nerf Turret

See how we built it, including our materials, code, and supplemental instructions, on Hackster.io: https://www.hackster.io/hackershack/r... In this video we show you how to build a DIY motion tracking airsoft (or nerf gun) turret with a raspberry pi 3. The airsoft turret is autonomous so it moves and fires the gun when it detects motion. There is also an interactive mode so that you can control it manually from your keyboard. We used an airsoft gun for this project, but you can easily change modify this build to use a Nerf instead. This project is small, lightweight and entirely battery operated. We created two separate operation modes: Interactive and Motion Detection. Interactive allows you to control the turret remotely and stream live video. Motion Detection uses openCV and computer vision to track moving targets in front of the camera. Since this device fires projectiles, please use the necessary safety precautions while operating the turret. :) Get a full parts list and written instructions on Hackster.io: https://www.hackster.io/hackershack/r...
