This 125 pound monster brings a whole new meaning to Death Metal. This beast is absolutely unstoppable. using five IR sensors across the solid aluminum front bumper, it can find its opponent within seconds. Once it does, it proceeds to use all four of its electric motors to drive them out of the ring and, sometimes, out of commission.
Perhaps the most twisted branch of the rube family tree, FrankenRube is a monster to be reckoned with. With a history almost as filled in as its opponents are with dents, FrankenRube has quite a record of victories, including first place finishes at NRC 2010 and NEIRG 2011. This diamond plated steel shell holds the most ferocious three kilograms you have ever seen. Beware.
