Pharaoh was a Middleweight robot with an initially pyramid shape that was built by Team Pharaoh from the University of Puerto Rico to compete at the BattleBots Collegiate Championship in 2009 and was armed with a CO2-powered flipper. Later, Pharaoh was completely redesigned to be a box-shaped robot armed with a pneumatic ram. It is unknown how well Pharaoh did in this competition.
