SwarmTurret: WiFi Controlled Foam Dart Turret
prusaprinters
<p>I built a 3D printed foam dart turret with streaming video controlled from any web browser on the local WiFi network. It's powered by a raspberry pi 4 and three servos for the X axis, Y axis and firing control. You can see a video of it in action <a href="https://www.youtube.com/shorts/W1DCnf5MDu8">here</a> and more details on the hardware build can be found <a href="https://alexmeub.com/building-a-web-controlled-nerf-turret/">here</a>.</p><p>The internals of the firing mechanism are from a Nerf Swarmfire, a blaster I selected because it uses a motorized direct plunger rather than a loud flywheel that takes time get up to speed. I designed most of the parts myself in Fusion 360 although the base was taken from an existing<a href="https://www.thingiverse.com/thing:5213801"> rotary display table project</a>.</p><p>The turret has a dedicated mobile and desktop web interface that is immediately accessible on my local network (if someone else is not already connected to it). Code is available <a href="https://github.com/meub/swarm-turret">here</a>.<br> </p><p>The assembly of the parts should be rather self explanatory but I plan to add more pictures and description to this when I have time.<br> </p><h4>Components</h4><ul><li>Raspberry Pi 4</li><li><a href="https://www.adafruit.com/product/2327">Adafruit Servo HAT</a></li><li>Nerf Swarmfire</li><li>2x 18650 batteries and holder</li><li>2x <a href="https://www.amazon.com/gp/product/B076CNKQX4/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1">20KG High Torque Servos</a> for X and Y axis control</li><li><a href="https://www.amazon.com/Sipytoph-Helicopter-Airplane-Walking-Control/dp/B09185SC1W">SG90 Servo</a> for trigger</li><li>M3 Nuts (10+)</li><li>M3 Bolts of different lengths (8,12,20)</li><li><a href="https://www.amazon.com/gp/product/B07X5FV3QS">Y Axis Bearings</a> - 17mm ID, 40mm OD, 12mm Width</li><li><a href="https://www.amazon.com/Logitech-960-000585-HD-Webcam-C310/dp/B003LVZO8S">Logitech C310 Webcam</a></li><li><a href="https://www.amazon.com/gp/product/B08HYJTR54">8 x 150mm Steel Rod</a> for Y Axis Pivot</li><li><a href="https://www.amazon.com/gp/product/B0793P8XJK/">Right Angle USB Extender</a></li></ul><p> </p>
