Wheely Big Cheese was a robot with what was described as the largest flipper ever seen in Robot Wars (the robot itself was over a meter long, and most of its body was the flipper). Its wheels were covered in tungsten golf shoe studs. Wheely Big Cheese competed in Series 4 and Series 5, reaching the semi-finals on both occasions.
Wheely Big Cheese has been recorded as the most powerful flipper, capable of flipping up to 800kg. In perhaps its most famous battle in Series 5 with Axe Awe, Wheely Big Cheese threw Axe Awe through the air, over the arena wall and onto the ground from the middle of the arena. It was one of the few robots that had a flipper powerful enough to flip itself over on nearly every use, mainly because there wasn't anything behind the wheels. However its downfall was the titanium exposed wheels that were vulnerable to attack and often became dislodged or destroyed, leaving it unable to move.
