Not long ago, building a seemingly professional robot or remote control car required very expensive manufacturing tools or some serious skills from Dremel. Now, in the era of rc tank robots our modern and affordable consumer 3D printers, anyone can design and build their own high-quality robots at home. However, it is rare to see that all mechanical parts are 3D printed designs.
Miranda manufactures a variety of 3D printing robots and remote-controlled vehicles - earlier this year we covered his unconventional screw-driven fuel tank. However, it sounds strange, this version is actually more complicated. Although the screw drive is transforming rc robots an uncommon and unusual concept, it is quite mechanically simple. On the other hand, the tank requires interlocking components for the rails, which are also 3D printed.
As you would expect, the tank is controlled by a brushless motor that is controlled by the RC receiver. Those rotating the pulleys, which in turn rotate the driven sprocket of the tank track. Steering is as simple as providing one side with more power than the other side. Miranda still experienced iterations of the track design and added a belt tensioner to the best rc robots pulley system, but even now he has a fully 3D printed tank that can pass through loose sand as it works.
