The world's first humanoid robot half marathon flagged off in the Beijing Economic-Technological Development Area on April 19, representing an experiment in humanoid robots moving into the real world and practical applications.
Nearly 20 teams from cities across China competed with robots of different models, technologies and sizes vying on the over 21 kilometer course.
Tien Kung Ultra, developed by the National and Local Co-built Embodied AI Robotics Innovation Center, crossed the finish line at 10:11 am to win the championship with a total time of about two hours and 40 minutes. Noetix Robotics' N2 robot won the second place.
Tien Kung is about 1.8 meters tall and weighs about 55 kilograms. Its developers have been exploring the boundaries of torque and the rotational speed of robot joints to improve movement speed. The leg design has reduced the impact of high-frequency vibration shocks as the legs hit the ground, while the joints use air-cooling technology. The model also has optimized motion control algorithm.
While marathons challenge humans to push physical limitations, the robot marathon marks a new beginning for humanoid robot technology and industry.
