Flipper
Real Life Examples: T-Minus, Chaos 2
Game Examples: Scout, Sentinel (both DSL and Stock)
A kind of bot that is designed to flip an enemy over/around, either to immobilize or to fling out of the arena.
You can see flippers everywhere in Robot Wars.
Not that efficient in Robot Arena 2 damage-wise in most cases, since flipping doesn't really do much damage even as the enemy bot lands (unless into a hazard). A few flipper robots (especially Heavyweights) in DSL got around this problem by attaching weapons near the top of the front (see CRITICAL EMERGENCY). Even then though, the damage isn't exactly very high. You might want to be careful if you're fighting on tabletop matches against a flipper - they could potentially get under your bot, and then you'll very likely end up out of the arena. Flippers are especially annoying in the Heavyweight division, where flippers can dedicate plenty of power to their flipper without too much of a sacrifice to their battery power or armor.
Popups are somewhat similar to flippers, but their wedges are not used to flip bots - instead, they have other burst motors dedicated to weaponary, basically a wedged, gut-ripping Hammer of sorts. Naturally, because of the greater damage Popups deal (and because most people play in the Combat Arena) - flippers are hardly ever built.
