It 2008 the intrepid little robot climbed out of the Grand Canyon. In 2009 he completed the 24 hours of LeMans on a tricycle. This time Panasonic is going to showcase their battery technology with a 500KM journey for their little robot that could. His journey from Kyoto to Tokyo is set to begin on September 23. Apparently details (page in japanese) are still thin, and some recharging will be involved, but still it should be interesting to see what they manage to pull off.
