This tank does not require a single bolt or nut. You just print the parts, put them together, connect the motors and electronics, and it's ready for battle. It shows excellent off-road capabilities, and turns on a dime. Each of this tank's two tracks is printed in a single piece, thus eliminating the need for assembly hardware.

The machine shown in the video below is powered with a Picaxe 20M2 microcontroller installed on a 300-hole mini-breadboard. There is also an H-bridge motor driver, an IR sensor, a couple of resistors and capacitors, and a whole bunch of jump cables. The entire set of electronic components used here can be bought on eBay for just a few dollars. The tank is operated with a regular Sony TV remote control.
