A robot from Cornell University has set a new distance record for a walking robot. The three-legged Cornell Ranger travelled a little over 9 km (5.6 miles) around the Barton Hall running track.
This was their second attempt to break the existing record, their previous attempt travelling a little over 1 km (0.62 miles).
The robot's gait took inspiration from humans, using the powered ankles to provide push off and a combination of momentum and gravity to move the legs. This made the robot extremely power efficient, helping it go the distance.
