Hypno-Disc, one of the pioneers of Heavy Rotating Weapons

Heavy Rotating Weapons are a range of large rotating weapons used throughout Robot Wars. They vary from flywheels, drums and rotating blades, to spinners encompassing the robot's entire body. Heavy rotating weapons are capable of causing substantial damage to opponents, and are some of the most destructive weapons ever to have been seen on the show.

Many heavy rotating weapons are compatible with invertible designs, although some robots with them require a self-righting mechanism or are unable to accommodate one due to their designs.
