Tetanus was a series of three robots from Shropshire that competed from Series 5 through 7 of Robot Wars. Although they shared the same name, the three robots were very different from one another. The team also entered Series 3 with the axlebot Flip Flop Fly. Strangely, every time either Flip Flop Fly or one of the Tetanus machines lost a battle in the main competition, the robot who beat it would eventually lose to that series' runner-up.
