Do not think mountain climbing is the movement of older talent to do, in fact, climbing is great exercise, and taking advantage of the hiking opportunities in touch with nature, are very beneficial for the body and mind. Climbing for the entire foot, especially the heels of the great pressure, if the mountain does not break easily produce half-way heel inflammation.

The Runbot can successfully walk up slopes, which could lead to improved Walking is an extraordinarily complex task that most bionics for humans. Credit: Florentin humans master, but robots still struggle with it. Rugged Wotorgotter et al. terrain makes walking even more difficult, but kids, hikers and others naturally learn how to adapt their gait to changes such as going uphill and downhill or traversing icy and sandy ground. Researchers have now simulated the principles underlying this adaptability and plugged them into the "Runbot." This machine is the fastest robot on two legs for its size, walking up to 3.5 leg-lengths per second with legs 9 inches long. (The Olympic speed record for human walking is 4 to 5 leg-lengths per second.) Unlike Honda's walking robot ASIMO, RunBot is a "dynamic walker," which means it does not calculate exactly where it will go in advance, saving on the amount of computer power needed. With its infrared eye, RunBot can detect a slope on its path. On its first ascent up a slope, RunBot typically falls over backwards, as it has not yet learned to react to what it sees with a change in gait. Computational neuroscientist Florentin Wörgötter at the University of Göttingen recalled hearing RunBot falling over and over again in his student Tao Geng's lab, as the song "Greensleeves" played "from some MP3 file on endless repeat. I still remember my frustration when I always heard 'thump thump thump, crash,' intermixed with the soothing sounds of this song " http://newstaging.livescience.com/technology/070712_robot_mountaineer.html 19/07/2007 Smart Robot Learns to Climb Mountains | LiveScience Page 2 of 3 machine successfully handles slopes after a few tries, adjusting its gait on the spot. Just as a human, it leans forwards slightly and uses shorter steps. The steeper the slope, the more RunBot will adapt its gait, findings Wörgötter and his colleagues detailed July 13 in the journal PLoS Computational Biology. http://newstaging.livescience.com/technology/070712_robot_mountaineer.html 19/07/2007 Smart Robot Learns to Climb Mountains | LiveScience Page 3 of 3 Space / Animals / Health / Environment / Technology / History / Strange News / Videos / Trivia & Quizze Sitemap | About Us | Conta http://newstaging.livescience.com/technology/070712_robot_mountaineer.html 19/07/2007
