notable robot, along with Vector ( a U.S. beetleweight). Notable British robots of this type are Carbide, the British equivalent of Tombstone. Full Body Spinner – Taking the concept of the spinner to the extreme, a full-body spinner (AKA shell spinner or tuna can spinner) rotates the entire outer shell of the robot as a stored energy weapon. Other robot components (batteries, weapon motor casing) may be attached to the shell to increase the spinning mass while keeping the mass of the drive train to a minimum. Full body spinners require time to spin the weapon up to speed, typically cannot self-right, and can be unstable — the original (2000–2005) BattleBots competitor Mauler being an infamous example (though its stability issues were eventually resolved by 2002), with the slightly more recent debutants Shrederator (2003-2006, 2014-present) and Megabyte (2002-2009, 2017-present), having a great deal of success in the live circuit, the former eventually making its televised debut in BattleBots under the name Captain Shrederator (which competed in all three ABC/Discovery/Science Channel 2010s seasons), and the latter making its televised debut in King of Bots. As of 2018, “Gigabyte”, a more powerful version of its predecessor “Megabyte”, competed in Battlebots with a directional pole also used for self-righting purposes, and achieved decent success, reaching the Round of 16 in Season 10 of the show, and defeating former Battlebots champ “Son of Whyachi” in the “Bounty Hunters” tournament. The 1995 US Robot Wars heavyweight co-champion Blendo was the first effective full-body spinner. A variant, the ring spinner, features a narrower spinning ring surrounding the robot; these designs have the advantage of being invertible. BattleBots 2016 competitor The Ringmaster is an example of a ring-spinner. Melty-Brain Spinner – A variation of the full-body spinner, where a robot's electronics allow it to drive in such a way that the entire robot rotates while it can move towards an opponent. This kind of design tends to be incorporated into invertible builds and requires a spin-up time like other spinners. One of the earliest known examples of this kind of robot is BattleBots lightweight quarter-finalist Herr Gepoünden, which managed to compete all the way till 2017, where by that point, very few thwackbots competed in its weight class. However, the first and best known Heavyweight Melty-Brain Spinner is Nuts 2, which had chains connected to two "flail" weapons on either side of the machine. This wasn't very
