The tank is designed in a way that it can be almost completely 3D-printed. It's of course inevitable to truly completely 3D print the tank so there are small additional parts needed like bearings, shafts, screws, bolts and nuts. The tracks/treads however are completely 3D-printed and don't need little shafts between every link. They are designed to snap together and stay together. It's very hard to take them apart after they snapped together, which is of course the intention.
Original 2 12V 1000 RPM motors were used but they turned out to be to weak so some new motors were used which are the same size but instead of 1000 RPM they are now 100 RPM.
The 2 motors are currently being driven by one L298N motor driver which is controlled by an Arduino Nano V3. The Arduino reads the data from 2 channels on the Spektrum receiver. It's possible to replace the L298N motor driver with 2 car esc's.
In front of the tank is a camera which is placed inside an "eye" so the driver can look up and down. The up and down movement of the "eye" is obtained by a standard 9g servo. The video feed gets transmitted through a 600mW 5.8gHz transmitter and gets send to some FPV goggles.
One of things that differs this tank from others are the treads which snap together and don't need any additional shafts to keep them together.
The small section in the body, right behind the eye was prone to breaking in the V1 version of the body, This should be fixed in the V2 version of the body.
The hatch on top of the tank gets hold on by 2 neodymium magnets (1 in the body, 1 in the hatch).
