Senju Winner of All Japan International Robot Sumo December 2014 (26th)


I started to design with my team (H-Tech Robot Team) at the beginning of first moths of 2014 at Istanbul, Turkey.

Senju Robot won 4th degree at 26th (2014) All International Robot Sumo Tournament. The tournament which held at Tokyo, Japan.



All Mechanics is custom designed. I used aluminum and steel for mechanics.


Magnet Locations.


We designed Mosfet H Bridge circuit for controlling Maxon DCX motors.

    Hello, just one question, how is it possible to arrive to 6.5m/s with those motors and that reduction? … I can’t understand.

    Hello fellow robot designer, I noticed in your chassis there are no line sensors. How does your robot can stay in the limit of the arena?

    Hey, do you know if there are any such events in the Czech Republic? I don’t know anyone practicing this so there’s not someone I can really talk to about the mini sumo robots, how to build them or a training partner. This is a great sport, too bad it’s not more known and not more people are doing this.

    I always wanted to participate in such events, but in my university, they don’t organize such kind of events. But thank to you that we are able to watch great videos and it inspires us so much.
