HEBOCON
Japanese robotics fighting contest where the makers have no technical skills and the robots have to be as crappy as possible.

Hebocon is a robot sumo-wrestling tournament for those who don’t have the technical skills to actually make robots.
31 pseudo-robots that don’t even move properly came together to go head to head.
The robots in this tournament are nothing like what their builders initially imagined them to be, robots are forgotten on the train, the strategies made with careful planning only result in failure, and the entrants who enter the ring brag about their robot’s secret moves that don’t really exist.
This is the heated battle between crappy, but lovable robots.
