RAIBO 2, developed by a research team from the Korea Advanced Institute of Science & Technology (KAIST), has become the first four-legged robot in the world to finish a full marathon, showcasing its walking control technology and durability. It participated in the 22nd Sangju Marathon, completing the 42.195-kilometer course in four hours, 19 minutes and 52 seconds.
The course includes two 50-meter-high hills at the 14-km and 28-km marks, making it a challenging route for runners and for quadruped robots due to unexpected obstacles. The team, used an advanced learning algorithm for RAIBO 2, allowing it to train its walking mechanism in an environmental simulation to replicate diverse terrains such as slopes, stairs and icy paths.
