RC FPV tank rover

One of key features that sets this tank apart from others are the treads which snap together seamlessly, requiring no additional shafts to keep them intact. A small section in the body, located right behind the eye, was prone to breaking in V1 version of the body. This issue should be resolved in V2 version of the body. I designed the tank with 3D printing in mind. While it's not entirely possible to completely 3D print the tank, there are some small additional parts needed such as bearings, shafts, screws, bolts and nuts. The tracks, however, are completely 3D printed and don't require little shafts between every link. They're designed to snap together and stay that way, making it very hard to take them apart once they've snapped together - which is exactly what I intended. Initially, I used two 12V 1000 RPM motors but they turned out to be too weak, so I ordered new motors of the same size but with a much slower speed of 100 RPM. If I wanted to install bigger motors in it, I would have had to completely redesign the tank, which would've taken up too much time since I'd already 3D printed all the parts. The two motors are currently being powered by one L298N motor driver which is controlled by an Arduino Nano V3. The Arduino reads data from two channels on the Spektrum receiver. I might replace the Arduino and motor driver with two car ESCs, but it's also possible that I'll stick with the Arduino so I can connect some sensors to it and make the tank perform tasks autonomously. In front of the tank is a camera placed inside an "eye" so the driver can look up and down. The up and down movement of the "eye" is achieved by a standard 9g servo. The video feed gets transmitted through a 600mW 5.8GHz transmitter and sent to some FPV goggles. The hatch on top of the tank is held in place by two neodymium magnets, one in the body and one in the hatch.
