Robot Dog Runs a Marathon on a Single Battery Charge
- On Nov. 17, 2024, the quadrupedal robot RAIBO2 completed the 42-kilometer Sangju Dried Persimmon Marathon without recharging or swapping its battery, finishing in 4 hours, 19 minutes and 52 seconds.
- Engineers at KAIST, led by Professor Hwangbo Je-min, addressed energy bottlenecks by reducing leg weight and improving motor efficiency, enabling the machine to navigate asphalt roads and inclines.
- The machine consumed roughly 1,280 watt-hours of electricity and requires less energy to carry a kilogram over one meter than the average human runner, demonstrating superior efficiency.
- Raion Robotics is already moving to mass-produce the platform for disaster recovery and industrial inspections, though lead author Choongin Lee cautions that adding onboard autonomy will increase power consumption.
- Katie Byl, an engineer at the University of California, Santa Barbara, notes humanoid robots require a 'mobile pit crew' for battery swaps, as RAIBO2's team aims to extend range to 65 kilometers.

The Independent (US)Scientists reveal findings from the first robot to ever run a marathon
Pioneering run could lead to new kinds of robots for more functional purposes, scientists behind it say
For the first time, a four-legged robot outside the laboratory completes an official marathon - with only one battery charge. "Raibo2" takes about 4 hours and 19 minutes. South Korean developers already see concrete areas of application for their machine.
A four-legged robot took part in a marathon in South Korea – and managed it in about four hours and 19 minutes with just one battery charge.
With one charge of electricity and one suitable time for hobby runners: Researchers in South Korea have run a four-legged robot for a marathon. They already have an idea how to use »Raibo2«.
Complete a marathon in 4 hours and 19 minutes, on four legs and with a single battery charge. That is the feat of RAIBO 2, not so much for the time, but for the energy efficiency, with an autonomy about three times that of quadruped robots. The advances in the...
