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.
- 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.
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
- 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.
- 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.
List of Sit-and-Spin RobotsEdit

|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|
