Spin Doctor rips off Matilda's tusk.

Spin Doctor snaps off Matilda's tusk

Sit-and-spin robots are one of two forms of thwackbot to appear in Robot Wars. They work under the same principle as a full-body spinner, in that the entire robot is designed to act as a heavy spinning object which makes contact over a small surface area.

DefinitionEdit

  • Sit-and-Spin refers to any robot whose only method of attack is to spin on its own axis in hope of damaging opponents when they drive close to it. Most sit-and-spin robots were armed with a sharp or blunt weapon along their ends or edges to facilitate damage, while others featured a circular body with spikes, blades or sharp edges along its sides.

MeltybrainEdit

Cyclonebot

Cyclone, the US pioneer of "Meltybrain" technology

The sit-and-spin concept waned in popularity as more advanced and effective spinning weapons became more commonplace. In between both runs of Robot Wars, however, a builder in the US discovered a way to allow Sit-and-Spin robots to move and spin at the same time. This concept, known as Meltybrain technology, involves equipping a sit-and-spin robot with LEDs and a motion detection system, enabling the robot to calculate its position and move across the arena in a controlled manner while spinning. The Meltybrain concept would not be utilised by a Robot Wars competitor until Nuts 2 in Series 9, although a lack of testing prevented Team Nuts from using it in its televised appearance.

Advantages and DisadvantagesEdit

Advantages

Lizzard vs Project Two

Lizzard uses its sit-and-spin tail to attack Project Two: Hexem

  • Since the sit-and-spin design works under the same principles as a Full Body Spinner, in theory it should be just as devastating in effect. A notably potent sit-and-spin robot is first Dutch Robot Wars runner-up Lizzard, who used its tail to severely damage Neater's lifting forks in the Heat Final of the second series.
  • The sit-and-spin design provides a great degree of protection from attacks such as ramming, as it will often deflect the opponent upon contact with them. This was best shown in the Trial of Series 2 Heat E, as Matilda was unable to build up an effective charge in order to push Spin Doctor off the King of the Castle platform.

Disadvantages

Terrorhurtz vs Nuts

Terrorhurtz could easily remove Nuts' spinning flail, leaving Nuts with no way of damaging it.

  • While it is potent, a sit-and-spin cannot usually move and attack at the same time; to attack it must spin on the spot.
    • Spinning in place is not considered to be aggressive behavior, a fact that the judges will note if a match winner is to be chosen based on points.
    • However, this issue can be overcome through the use of Meltybrain technology.
  • In addition, if its wheel or drive becomes damaged, not only will its locomotion be crippled, but its weapon will too, since a Sit-and-Spin uses its drive system to attack.
  • Sit-and-spin robots were ineligible for the Seventh Wars, due to the moving weapons rule. However, controversy struck when T-Wrecks managed to qualify regardless.
  • Certain sit-and-spin robots were necessarily fragile, and their weapon could be easily damaged. This happened most infamously during Nuts' Head-to-Head battles with Carbide and Terrorhurtz, who were both able to remove the rotating ring and leave Nuts defenceless.

Robot Series Appearances as Sit-and-Spins Notes
Abaddon Series 3 Whipping tail, rolled on a castor which had to be changed before combat.
Ajjay Extreme 1 Was intended to be a full-body spinner, but instead resorted to a sit-and spin tactic.
Brawler US Season 2
Crasha Gnasha Series 3 Whipping tail
Dantomkia Series 6-8, Extreme 2 Spun at 450 rpm using the spikes at the front. Never really used. Was upgraded to 500RPM for Series 8, but was once again not really used
IDO Dutch Series 2
Impact Dutch Series 2 The hammer was covered in fur that was often set alight.
Lizzard Dutch Series 1-2 Whipping tail
Micro-Mute Extreme 2, Series 7 Relied more on its speed and wedge shape to win battles.
Mini Maul Series 7
Nuts Series 8-9 Rim can turn vertically independently, giving the robot a moving weapon. Returned to Series 9 as Nuts 2, utilising Meltybrain technology.
Spin Doctor Series 2 First Sit-and-Spin design. Managed to rip off one of Matilda's tusks.
