This site provides directions to build "The Beast" (shown to right) as well as advice on sensor configurations. This design had several advantages over the basic Trusty design. First its get old constantly repairing your robot and we wanted a design that was steardy. The beast manages to be durable enough, it is hard to pull apart, yet the batteries can be accessed fairly easily by pulling the entire roll cage off in one piece. As an added bonus the turing radius manages to be smaller and more consistant than the basic robot. So, the beast does more than just look cool, the design actually helped reduce the amount of work we needed to do in the long run.
