Summary of AUTO-AIMING NERF GUN TO GIVE YOU THE EDGE IN BATTLE
This article describes a DIY auto-aiming Nerf gun project by [3Dprintedlife], built upon an open-source design by [Captain Slug]. The system integrates a two-axis gimbal driven by stepper motors and controlled by an Arduino. A Raspberry Pi running OpenCV processes video from a camera module to track targets or faces, adjusting the aim automatically when the trigger is half-pressed. A servo mechanism releases the sear via microswitches upon firing. The project encourages learning robotics and computer vision, with all files available on GitHub for potential integration with remote-controlled tanks.
Parts used in the Auto-Aiming Nerf Gun:
- Open source Nerf gun design by Captain Slug
- Two-axis gimbal
- Pair of stepper motors
- Arduino controller
- Camera module
- Raspberry Pi
- OpenCV software
- Microswitches
- Servo motor
Ever wished for some robotic enhancements for your next nerf war? Well, it’s time to dig through the parts bin and build yourself a nerf gun with aimbot built right in, courtesy of [3Dprintedlife]. (Video, embedded below.)
The gun started with a design borrowed from [Captain Slug]’s awesome catalog of open source nerf guns. [3Dprintedlife] modified the design to include a two-axis gimbal between the lower and the upper, driven by a pair of stepper motors via an Arduino. For auto-aim, a camera module attached to a Raspberry Pi running OpenCV was added. When the user half-pressed the trigger, OpenCV will start tracking whatever was at the center of the frame and actively adjust the gimbal to keep the gun aimed at the object until the user fires. The trigger mechanism consists of a pair of microswitches that activate a servo to release the sear. It is also capable of tracking a moving target or any face that comes into view.
We think this is a really fun project, with a lot of things that can be learned in the process. Mount it on a remote control tank and you’d be able to wage some intense battles in your backyard. All the files are available on GitHub.
You are never too old for a good old nerf battle. Whether you want to be a sniper, a machine gunner, or a heavy weapons specialist, there’s a weapon to build for every role.

- How does the auto-aim feature work?
When the user half-presses the trigger, OpenCV tracks the center of the frame and adjusts the gimbal to keep the gun aimed at the object. - What hardware controls the gimbal movement?
A pair of stepper motors drives the two-axis gimbal between the lower and upper sections of the gun. - Which software is used for target tracking?
The Raspberry Pi runs OpenCV to detect and track moving targets or any face that comes into view. - How is the trigger mechanism activated?
A pair of microswitches activates a servo to release the sear when the user fires. - Can the gun track moving targets?
Yes, the system is capable of tracking a moving target or any face that enters the camera's view. - Where can I find the project files?
All files for the project are available on GitHub. - What is the base design for this project?
The gun started with a design borrowed from Captain Slug's catalog of open source Nerf guns. - Who modified the original design?
[3Dprintedlife] modified the design to include the robotic aiming components.
