BioHazard is a combat robot built by Carlo Bertocchini. It was the most successful robot in the heavyweight division of BattleBots. It originally competed in the U.S. Robot Wars where it won 2 heavyweight division titles. It went on to win 4 BattleBots championships. BioHazard's weapon is an electric four-bar lifting arm (technically, an asymmetric linear actuator) used to lift other robots. For much of its reign it was notorious for being difficult to attack and get under due to hinged titanium wedge skirts on all sides and low profile (4 inches tall). BioHazard initially retired in 2002 with a record of 37 head-to-head wins and three losses.
