Ithaca, N.Y. (UPI) Jul 20, 2010 A robot designed by U.S. engineering students set an unofficial untethered walking record of 14.3 miles at Cornell University in Ithaca, N.Y., the school says. Steered by students using a standard remote control unit for toys, the untethered Ranger robot covered the distance in 11 hours, making 108 laps around an indoor track at the university's Barton Hall on July 6, a university release said. The "walk" beat a previous record by a walking robot of 12.8 miles. Unlike other walking robots that use motors for every movement, Ranger emulates human walking, using gravity and momentum to help swing its legs forward, its designers say. Its gait resembles a human on crutches, alternately swinging two outside legs forward and then two inside ones. Experience learned from Ranger could be applied to rehabilitation, prosthetics for humans and improving athletic performance, Andy Ruina, Cornell professor of theoretical and applied mechanics, said.

New Zealand inventors produce bionic legs for paraplegicsWellington (AFP) July 16, 2010 Two New Zealand inventors have produced what they claim are the world's first robotic legs to help paraplegics walk again. The bionic legs were road-tested publicly for the first time Thursday by 23-year-old Hayden Allen who was told five years ago he would never walk again after being paralysed from the chest down in a motorcycle accident. Allen said the experience of being able to stan ... read more |
