Osaka-based robotics company Vstone has announced plans to hold a real marathon for bipedal robots, coinciding with the real Osaka Marathon. The robots must complete 422 laps of a 100 meter course (42.2km or 26.2 miles), from February 24th to 27th (10am to 8pm). Before you get too excited, the marathon will only star Vstone’s crop of small hobby and educational robot kits (RB2000, Robovie-X, Robovie-PC, and BeautoEV). The Robovie-PC and BeautoEV will tackle the course by autonomously following a line, while the others will be controlled by people. This challenge will really put the robot’s servo motors to the test, so the rules state that components can be swapped (if they break down), but not the entire robot. You’ll be able to watch the marathon live at Vstone’s UStream channel.
