Fun Fact
Human Beaten: RAIBO2 is the first legged robot to officially beat the human energy efficiency benchmark (cost of transport) during a long-distance run.
Glossary
regenerative braking (noun)
An energy recovery mechanism that slows a vehicle by converting its kinetic energy into usable electricity. The RAIBO2 robot utilized this system on downhill slopes during a November 2024 South Korean marathon.
