Hebocon is a popular Japanese robot sumo-wrestling competition for those who are not technically gifted. It is a competition where crappy robots that can just barely move gather and somehow manage to engage in odd, awkward battles.

UPDATE:  We will be playtesting the robots at the Northside Mini-Maker Faire – Learn about what we’re doing there.

Micro-Hebocon is a spinoff from the Flea Circus project.

The idea came while at a LegoFirst robotics, where I found myself redesigning the competition to be more improvised – simpler robots made (and re-made) in the gym during the competition.

I had seen the YouTube video https://www.youtube.com/watch?v=46ivFpsmEVQ&t=124s

So my version is a micro-hebocon, a 4-second wind-up robot battle – who fight in a 9″ inch ring.

You’d get a motor with the 3d printed gears, then you make ad hoc wheels out of rubberbands and cardboard. You make a chassis out of cardboard and duct tape.

The sumo ring:

It will be on a warped wood board. More randomness. Of many random warped wooden boards, one is selected. The ring is incredibly small, the radius will be decided base on test battles — ON April 15ish, we’ll do a test battle.



UPDATE:  A new variation/form of this robotics type, called “Fragile Robotics” has entered the fray. And worse yet, they are setting the rules. New limits on weight that make metal parts almost prohibitive.

Update: I’m going to playtest this at the Northside Makerfaire on 5/6
