KAIST's Four-Legged Robot Learns to Cross Rough Terrain and Climb Stairs Without Human Control

Researchers at Korea's KAIST have unveiled a four-legged robot that navigates stairs, forests and obstacles entirely on its own, switching between walking and leaping gaits in real time using only onboard sensors. The work, published in *Science Robotics*, marks a step toward quadruped machines that can adapt to unpredictable environments without a human operator at the controls.
