Ranger, similar in size to the robot above, completed 14.3 miles in about 11 hours.

Did you know that a new world record was just set? A walking robot, named Ranger, has just completed 14.3 miles.

A four-legged robot made 108.5 laps around a 1/8-mile indoor track at Cornell University. Ranger’s journey took 10 hours, 40 minutes, and 48 seconds to complete. Ranger was able to move using about a penny’s worth of electricity every 3 miles.

6 on-board microprocessors helped Ranger walk and steering was done by remote control. To protect the robot, foam padding was installed to make sure he was not injured during a fall.

Ranger may have set a distance award however, his pace was slow compared to BigDog. The robot, BigDog, was built to carry 300-pound loads. BigDog’s walking distance record is 12.8 miles.

Ranger and BigDog are just the beginning of this advanced technology. Getting the same amount of longevity with a single power source (without needing to be charged for a while) could mean great things for the future.
