Does anyone have any ideas or drawings on D.I.Y tank tracks for a robot. I know you can buy them commercially but that kind of defeats the creative fun in building your own robot. I have seen one D.I.Y track using bike chains and skate board wheels which looks great but I'm sure some of our EZ Robot makers out there have many other ways of making them. Presently I'm trying to use the same plastering metal angle stips that "Bob the robot" was built with and initial trials of connecting metal treads with nothing more than black plastic tape (the two drive wheels of the robot sit inside the tracks) and spin them by running on the inside of the tracks (much the way the skateboard wheels work inside the bike chains). see example at
Anyway, I've also seen people use door hinges and even wooden carved tracks, but it would greatly appreciated if we could share some different and innovative ways of building tracks.
