I got inspired by a tank project ProtoTank and by FPV Prototank with Turret
I reused a lot from ProtoTank and motified the parts a bit so that e.g. nuts and screw heads disappear in them. I also modified the tank tracks so that they've got more grip.
Unfortunately the tracks are a bit loose but it works. Next time I will choose a smaller diameter for the track parts.
As first draft I use an arduino uno and a motor driver shield from Adeept like in the project radio-controlled-arduino-devices, especially from the vehicle 4WD Car based on Adeept Board. I used exactly the same software because also the 4WD car has got 4 TT-Motors and works the same way.
Part list:
1x simpleBaseFrame.stl
2x ProtoTank_trackinnerFrame2.stl
2x ProtoTank_TrackOuterFrame2.stl
64x stud.stl
64x track2.stl
All screws and nuts are changed to M3.
Same tank with simpleBaseFrame2_5cm.stl
