Soteria

Gun Mechanism

Inspiration:

The increase of mass shootings in our generation.

What it does:

Decreases the amount of mass shootings by locking the gun when it has entered a no-gun zone.

How we built it:

To create Soteria, we dismantled the casing of a NERF gun, preserving the triggering mechanism which is similar to that of a real gun. Using the CAD software, Solidworks, we designed and 3D-printed a larger casing with room for the Arduino, Servo, and battery.

Challenges we ran into:

Finding the dimensions for the gun to CAD, getting GPS to work reliably, LED was not in-sync with the GPS, data collection (finding coordinates for the safe zone), and wiring the correct wires.

Accomplishments that we're proud of:

As beginner hackers, we were proud to have been able to finish the project and learn new things along the way.

What we learned:

We learned how to CAD, arduino, works with servos, work with GPS, and time management.

What's next for Soteria:

For future implementation we would like to include a WiFi module with the Google Maps API with arduino, instead of using a GPS, for more accurate positioning, and automatic classification of safe/unsafe zones. We would like to implement a better locking mechanism, where the trigger recedes into the gun. We want to make the overall design more sleek, and we want to implement a tampering chip that allows law enforcement to find any guns that were tampered with/had locking mechanism removed.
