biohazard

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.

Biological hazards, also known as biohazards, refer to biological substances that pose a threat to the health of living organisms, primarily that of humans. This can include medical waste or samples of a microorganism, virus or toxin (from a biological source) that can affect human health. It can also include substances harmful to other animals.
