Cornell’s Ranger Robot, world record holder for the longest walk by a robot on a single charge, has smashed its own personal best by logging 40.5 miles without stopping, recharging, or even being touched. Over the course of almost 31 hours, Ranger ambled along at a not-so-blazing 1.3 miles per hour for 397.75 laps around a running track, but managed to make the whole trek using just a nickel’s worth of electricity.
Slow and steady really does win the race. A diminutive robot perched atop stork-like legs has slowly strode beyond BigDog’s world record for robotic walking, making a continuous 11-hour trek around an indoor running track at Cornell University that covered 14.3 miles.
