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.
