Laibo 2, a quadruped robot developed in South Korea, has become the first robot to ever complete a full marathon on a single charge after running the 42.195-km Sangju Dried Persimmon Marathon.

Developed by Professor Hwangbo Je-min and his team at the Korea Advanced Insitute of Science and Technology, Laibo 2 is an advanced quadruped robot designed with a focus on endurance. It recently became the first robot to run a full marathon after completing the 22nd Sangju Dried Persimmon Marathon in Sangju, South Korea with a respectable time of 4 hours, 19 minutes, and 52 seconds, on a single charge. The 42-kg robot had to navigate difficult terrain, including two relatively steep hills, gauge its distance from the other runners, and maintain course, all the while mitigating power consumption to ensure it reached the finish line.
