=== Mini Sumo ===
In the  Mini Sumo class (also called Sumo 500g class) robots have a weight limit of up to 500 g and are limited to 10 cm x 10 cm, with no height limit. Once the fight starts, the robot is allowed to expand its size.<ref name=":4" />[[File:Mini-sumo no Brasil.jpg|thumb|Mini Sumo match.<ref>{{Cite web |title=ThundeRatz {{!}} Ônix |url=https://thunderatz.org/projects/robots/onix |access-date=2024-12-31 |website=thunderatz.org}}</ref>]]The dohyō should be a 2.5 cm in height circular wooden board with a diameter of 77 cm (including the white border line), covered by a formica laminate located on top. The arena is made of wood, and therefore the robots are not affected by the force of magnets.<ref>{{Cite web |title=Unified Sumo Robot Rules |url=http://robogames.net/rules/all-sumo.php |access-date=2024-12-31 |website=robogames.net}}</ref>

This class is also usually divided in Mini Sumo Auto (Autonomous) and Mini Sumo RC (Radio-controlled).<ref name=":4" />  

Since a Mini robot is more affordable than a 3kg robot (due to material costs and manufacturing dimensions), it is a more popular class and often considered entry-level. Because of this, it has become the most popular robot sumo class in the world.

Not an original class from All Japan Robot-Sumo Tournament, the class was added to the tournament as a test event in 2019, and officially added in 2023, introducing mini sumo to japanese builders.<ref>{{Cite web |title=第34回｜大会結果｜ここに歴史あり｜全日本ロボット相撲大会 - ALL JAPAN ROBOT-SUMO TOURNAMENT |url=https://www.fsi.co.jp/sumo/history/record/34/index.html |access-date=2024-12-31 |website=www.fsi.co.jp}}</ref>
