Mini-Tracker

thingiverse

This little tank was designed entirely within Fusion 360 and represents an advanced build. It can be controlled from any cell phone app over wifi, thanks to Blynk's robust interface. A detailed bill of materials has been included, with items sorted according to their relevance to the assembly pictures. Feel free to take this project as far as you like, printing out only the tracks to integrate into your existing vehicle or building it all the way up from scratch, including the body and turret. Customize it into a unique steampunk creation that reflects your personal style. The photo shows it with a drone fpv camera mounted in the turret, but I have yet to make the camera functional. If you decide to use this battery box design, consider using a pair of forceps as a heat sink when soldering the wires, as shown in the picture. Note that I've included upper track sliders instead of wheels on the model. However, if you prefer to substitute the small wheels, I've provided their stl files. Here's an essential assembly tip: it's crucial that the sprockets are properly aligned when glued to the sprocket hub. Start by gluing the first sprocket to the hub and pin 12 track sections together while the glue is drying. Once the glue is dry, glue the second sprocket to the hub and wrap the track section around the assembly while the glue is still wet. Regarding the twin battery box design, it was intended for two 18650 batteries wired in parallel. The Tamaya motors are rated at a maximum of 3.5v, so if you wire the batteries in series, you'll need to drop the voltage to the motors using a buck converter or another suitable method.
