A
Whirlybug is similar to an electric bumper car. It is round, with a bumper going all the way around. Unlike most bumper cars, however,
power is not provided by an overhead grid, but rather by alternating conducting plates that make up the floor of the court. Whirlybugs are more complex than traditional bumper cars, but this is necessary, as an overhead grid would obstruct play. A Whirlybug is
steered by a handle that looks like a crank. This handle allows steering not just side to side, but also backwards. One of the downsides to a Whirlybug's controls is the difficulty beginners will almost certainly have with them. One reason is that there is technically no reverse, which can make for an extremely difficult situation for a beginner who has run into a wall. A player must apply the throttle as they are twisting the handle in either direction. After a single rotation, the drive train reverses, and the car moves away from the wall. More experienced players may simply twist the crank a single time and then apply the throttle. The other problem with steering is that Whirlybugs often do not center the crank automatically, making it difficult for beginners to recover from a very tight turn or from "reverse". Once the particulars of the steering are learned—usually in one or two games—the controls tend to be easy to use. ==Terminology==
