U.R.O., standing for Unidentified Rotating Object, was a robot from West Sussex that fought in the Seventh Wars. It was entered by Team M.I.B.O. (Men in Black Overalls). It lost in the first round, having been paired with the very experienced Bigger Brother and soon-to-be champion Typhoon 2. U.R.O. was updated with new armour and internals, including a belt drive for the disc to replace the chain after Series 7 in preparation for the next series, but the show was put on hiatus for 12 years. Team captain Mark Stringer still owns the robot.
