   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 "

   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.

Description: 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.
