A four-legged robot, dubbed Ranger, has just set a new distance record for robots, walking 14.3 miles before it finally ran out of juice. The record-breaking journey took a good 10 hours, 40 minutes, 48 seconds, and used about a penny’s worth of electricity for every 3 miles that it covered. The robot’s steps are coordinated by six on-board microprocessors, though it’s steered by a remote control. In case you’re wondering, the “eyes” and “ears” that you see on the robot aren’t actual sensors, rather they’re foam paddings, designed to protect the robot in case it falls. Check out a video of Ranger in action after the jump.
