Mini Breadboard Tank Robot
thingiverse
This is a small, treaded robot that can hold two miniature breadboards on top. It is powered by standard N20 motors and has ample room for a 3S battery inside. The tank tracks (#43903) and wheels (#13971) are standard LEGO parts, making the entire robot very easy to build. To see how it's assembled, I have another one listed below. You'll need the following materials: Four M2x20mm screws Two M2X12mm screws Four M2x8mm screws Four M2x6mm screws Two N20 motors (I recommend 600rpm 12v) Here are some links to where I bought my parts: N20 motors - https://www.aliexpress.com/item/DC-12V-600RPM-Micro-Speed-Reduction-Gear-Motor-Metal-Gearbox-Wheel-Shaft/32674463757.html Tank tracks - https://www.brickowl.com/catalog/lego-technic-tread-small-with-20-tread-links-43903 Wheels - https://www.brickowl.com/catalog/lego-medium-stone-gray-rim-narrow-18-x-7-and-pin-hole-with-deep-spokes-and-brake-rotor-13971
