THE RINGMASTER is the 250 pound robot I designed and built for Season 2 of BattleBots, a prime time TV show on ABC. The bot features a steel ring that spins around the center chassis, and a unique vector skid drive system that resists counter-rotating when the weapon hits an opponent. May daughter Hannah drove The Ringmaster during the competition.
