Floor Jack.
Floor Jack was a Middleweight robot built by Team Van Cleve, and Team Coolrobots that attempted to compete at ROBOLympics 2004. It was a invertible, two wheeled, silver, wedge shaped robot armed with a pneumatic flipping arm. However, Team Van Cleve wound up pulling out of ROBOLympics 2004 in favor of competing at the BattleBots hosted NPC Charity Open the same year, and Floor Jack retired after that event, never to make a single RoboGames or ComBots appearance until being brought out of retirement to register for RoboGames 2023.
