Energieeffiziente Technik: Roboter in Südkorea läuft Marathon unter viereinhalb Stunden

Seoul, South Korea - A quadruped robot named "Raibo2" recently completed a marathon in the city, finishing the race in roughly 4 hours and 19 minutes with just one battery charge, according to research from the Korea Advanced Institute of Science and Technology (KAIST) in Daejeon. The findings, published in the journal "Nature," show that Raibo2 outperformed other quadruped robots by a significant margin in terms of range, potentially allowing it to travel an additional 25 kilometers after crossing the finish line.

This achievement comes nearly two years after the previous record, as no quadruped robot had successfully completed a marathon over 42 kilometers in an official event outside of laboratory settings. The scientists attribute Raibo2's efficiency to several factors, including lighter robot legs, optimized drive circuits, and movement patterns trained through machine learning.

While quadruped robots have the advantage of navigating rough terrain and mountainous regions, they generally require more energy due to the need to counteract their own weight with each step. However, Raibo2's extended range could open up new applications for quadruped robots, such as delivery tasks, patrols, and search and rescue operations in mountainous or disaster-stricken areas.
