Double-tracked is my attempt at a robust tank using the rubber treads. I used the rubber treads instead of the hard plastic treads since they have much better grip (and I have no plastic treads). This worked very well. The only down side to this is that there was no suspension. Also, the gears connecting the front and back treads would often catch on the ground. Overall though, I think this could outperform almost any other Lego tank the same size with hard plastic treads.

    Sure gets the job done.

    Simple - effective - great work.

    I love it! This thing can literally go anywhere!
    Maybe you could add extra tracks on the top so it continues to circulate when it tips over.
    P.S: What remote do you use for your NXT?

    Love the simplicity of the design! And because it uses rubber treads! Plastic treads are lousy if you need it to act like a tank :D
