The other day, I made some posts about “the world’s first bipedal robot full marathon” on the JAPAN Style Facebook page. And today, I would like to write about it in detail with a lot of photos and video ^^!

The bipedal robot marathon took place on Feb 24 in Osaka. Five robots ran the winding inside track. See the diagram below.

 

100 meters in circuit x 422 times (only the last lap is 95 meters) = 42.195 km

 

Mechanical maintenance, battery charging or servo motor changing, etc. was allowed. However, the robot body itself couldn’t be replaced. The maintenance time was included in the running time.
