Some of our sumo robot matches from Minoan Robot Sports Competition Global Olympiad 2026 that held at 3-6 April 2026 Crete - Greece.

JSumo, our team won 1st and 2nd place (3rd Lithuania, 4th France). Many robotics teams from Jordan, Romania, Latvia, Türkiye, Lithuania and France competed in the competition.

At the last Azerbaijan robotics competition (AIRO 2026), our high power MOSFET design used in the Reactor achieved 135A current levels at 12S LiPo (50.4V) per motor channel at matches.

This is a significant advantage compared to many DC motor drivers that typically operate in the 30A to 50A range. If your robot's performance is limited by motor driver current, we highly recommend taking a look at the Reactor. It has been successfully used in numerous robotics projects around the world.

Gears ⚙️⚙️? Yes, we have full stocks at jsumo shop.
We carry good selection of hardened steel gears for extreme impact resistance. If you need help on deciding for your next project drop us pm.

At picture 0.8 module gears shown (this module of 0.8 suggested for presicion and torque transfer)

14T Motor pinion gear (we have 5mm and 6mm hole diameter options)
14/50T concentric double gear (made from 1 mono lock steel body)
42T spur wheel gear (biggest size recommended for 40mm wheels).
