Full Body Drums are a robot related to crawlers but with shell spinner-like weapons.

They generally do use only 2 drive motors, and then add discs, extenders and weapons in a way that the chassis is enclosed in 2 shells with weapons on the outside.

Three variations do exist. The one without wheels (you must use the largest possible however) has weapons that touch the ground, making it really just an unusual crawler. The one with wheels (attached to the drive motors as well) must touch the ground with the wheels, not the shell/weapons. Benefit of wheels include highly increased grip and speed. Madman3 created a spinoff robot type, the TRFBD which used two DSL Discs as wheels, with the chassis spinning rather than any sort weapon motor. The saves weight and also makes it far less havoky, as well as allowing the chassis to be far higher, usually out of the reach of gutrippers and rammers. Flails are also an option for making it extra deadly.

They also can use a thwacker-style tail for stabilizing the chassis or for use as a Torque reaction hammer weapon.
