Fusion42 · 23 September 2026 · Fusion42 review

Lion Robotics, a KAIST startup, has published a paper in Nature reporting that their quadruped robot Raibo2 completed a full marathon (42.195 km) on a single battery charge, setting a new efficiency benchmark in robotics with energy performance exceeding competitors from the US and China.

This Wire brief sits within Fusion42's coverage of Robotics.

◆ ◆ The Wire takeaway

Energy efficiency in robotics is now a competitive frontier with Raibo2 showing how AI gait control and system integration can triple travel distance per battery charge. You should explore adopting similar AI-driven energy optimisation if your hardware depends on mobility or endurance.
