Ah... on HDPE (the same material that plastic cream cheese boxes are made out of) it does very well. The tread material is made out of the same conveyor material that factories which produce HDPE products use. YAY!

Oh, hey.. don't knock the ghetto-bots... our first year bot was made entirely out of wood... in someone's garage. The second robot was made at a machine shop by us... but still managed to look ghetto-fabulous... oh... and it never moved (!)

This robot was back to the garage... one quarter of a garage, actually... all we used on it are hacksaws, wrenches, chain breakers, and other stuff commonly found in every garage. Planning is the key to a successful robot.
