    This is just beyond awesomness! so creative!

    How did you get from tires to track chain? Looks great, just this one step missing.

    It's what you get when you cut cardboard in half, all the corrugations.

    Good work!

    Do you use one switch or two?

    amazing! such creativity.

    Thanks for your support...If any questions while making please comment.


    You could have one motor drive the left track and the other run the right track and add another switch so that they can be run independently. Then you'd be able to steer it using a combination of the two switches. It would be easier to steer with some other type of switches, though. Maybe even use switches that would allow it to go in reverse, too.
