University robot sets walking record

ITHACA, N.Y., May 10 (UPI) -- A Cornell University robot has set a world record by walking more than 40 miles on one battery charge and without human assistance, school officials said.

The bipedal Ranger robot, built and programmed in Cornell's Biorobotics and Locomotion lab, walked around Cornell's Barton Hall track for 30 hours, 49 minutes and 2 seconds last week, a Cornell release reported Tuesday.

It made 307 circuits of the track at a speed of 1.3 mph, its builders said.

Ranger's previous record was 14.3 miles, set last July.

The robot's total weight is 22 pounds, of which 6 pounds are the lithium-ion batteries that power the electronics and the motors.

The goal for this attempt was to have a robot walk a full marathon (26.2 miles) without recharge, and Ranger did that in a little more than 20 hours -- and then kept going until it recorded 40.5 miles.

"We were getting pretty tired by the end," said Violeta Juarez Crow, an electrical engineering major on the robot team.
