Tanque oruga mini

thingiverse

I'm building a tank, and I want to add an Arduino board on top. The wheels are stuck together with glue so that there's a groove for the rubber gasket to fit in. It comes with two miniaturized continuous rotation servos. The rear fender is not symmetrical, so I had to glue it from behind where the battery goes. To secure the Arduino board, I used double-sided tape on both sides. To tighten the orugas, I made the front axle movable by loosening the M3 screws underneath it. The wheels spin freely on 2.5 mm long metric bolts, but you might need to use a file to smooth out the hole in the wheel so that the bolt fits snugly and spins smoothly. It's essential to center the front axle well so that the orugas don't fall off. The rear wheels are stuck with glue to the supports that come with all the servos. I bought the orugas here: http://es.opitec.com/opitec-web/articleNumber/804925/zz/cID/c3I6b3J1Z2, and the continuous rotation servos here: http://www.electan.com/feetech-fs90r-micro-continuous-rotation-servo-p-6173.html. A video of it in action is here: https://youtu.be/y36uUW7gMyY
