Safety Factor is a heavyweight robot that participated in the 2009 BattleBots competition held in Vallejo, CA. It was an invertible box-shaped robot equipped with a standard drum spinner weapon. It didn't do very well in competition, winning only one match in the bracket.
Safety Factor was built by Andrea Suarez and Mike Gellatly, who would also enter Category 5 into the Collegiate Championship at the same event. The pair would also go on to build Witch Doctor for the television re-boot.
