  "account": "A four-legged robot called \"Raibo2\" completed a marathon in South Korea in approximately 4 hours and 19 minutes with only one battery charge. The robot, developed by the Korea Advanced Institute of Science and Technology (KAIST) in Daejeon, demonstrated a significant range improvement compared to other four-legged robots. After crossing the finish line, \"Raibo2\" still had enough energy to run an additional 25 kilometers. According to the researchers, the robot's efficiency was achieved through lighter robot legs, optimized drive systems, and motion sequences trained using machine learning. This advancement may expand the application areas for four-legged robots, including delivery, patrol, and rescue tasks in mountainous and disaster areas.",
  "summary": "Passable time and only one battery charge: Surrounded by human runners, a four-legged robot has completed a marathon. The team hopes that \"Raibo2\" could be used for patrols.",
