BOE-Bot with Tank Treads. For me, this was a disappointing add on for the BOE-Bot. The tracks are from the Tamiya Track & Wheel set and are mounted on a custom designed bracket. The tracks stretch and since the bracket provides no means to adjust the tracks to maintain tension, they invariably fall off. Needless to say, this particular BOE-Bot got its wheels back. See the MatTracks addition for a super treaded BOE-Bot.
