can throw opponents end-over-end through the air causing damage from the landing impact or, in Robot Wars, toss it completely out of the arena. Flippers use a large volume of compressed gas and often have a limited number of effective attacks before their supply runs low. The two-time Robot Wars champion Chaos 2 and original, 2000s-era BattleBots superheavyweight champion Toro and middleweight competitor T-Minus were flippers, as is the same Team Inertia's more recent heavyweight robot Bronco, with both T-Minus and Bronco capable of self-righting with their powerful pneumatic flippers. Hydraulic flippers, while not "common" in robot combat, have managed to start achieving some degree of success, as with Team Whyachi's flipper Hydra, which gave Bronco a serious challenge in the 2019 BattleBots competition. Other solutions include e.g. utilizing internal flywheels, as shown by the success of Team Seems Reasonable's flipper Blip in the 2021 BattleBots competition. While most flippers operate with the pneumatic arm hinged at the machine's rear, Robot Wars' Firestorm achieved remarkable success with a front-hinged flipper, placing third in Robot Wars on three separate occasions (Series 3, 5, and 6) never failing to advance to the series' semifinal rounds, flipping a total of 7 out of the arena (the only heavyweight robot to flip another out of the arena with a front-hinged flipper) and having the most UK championship competition fight wins, of 23, as well as winning the second-most fights out of any competitor/series of competitors on UK Robot Wars, with only Razer having more wins overall. Stabber – Mechanically similar to the flipper is the stabber, which throws or stabs opponents forward instead of upward. An effective stabber can penetrate into the opponent, damage vital inner parts. When they fail to penetrate, they throw their opponent back across the arena into walls or hazards. Stabbers typically use a large volume of compressed gas, which limits the number of times they can fire their weapon in a fight. BattleBots super heavyweight Rammstein was a stabber. Clamper – Another lifter variant, the clamper adds an arm or claw that descends from above to secure the opposing robot in place on a lifting platform. The entire assembly then lifts and carries the opponent wherever the operator pleases. Two-time BattleBots super heavyweight champion Diesector was an electric clamper, as well as middleweight runner-up Complete Control. Dustpan – An uncommon variant on the clamper, the dustpan simplifies the design
