How did Bigger Brother beat Mauler in the USA? I know the answer, if you want to find out for yourself, go to http://www.battlebots.comwww.battlebots.com and search under Bigger Brother & check out the video of their match against Mauler. But if you want it from my view, Mauler hit Bigger Brother, it was deflected onto the kill saws, the saw sliced at one of Maulers blades, the robot became very unstable and it flipped itself over breaking the forces of gravity.
