On May 24, Panasonic showed off the capacity of their Evolta AA batteries by using them to power a cute little mascot robot as he scaled a 530 meter cliff in the Grand Canyon. The grueling climb took the little (17 cm, 130g) robot 6 hours and 45 minutes and was recognized by the Guinness Book as the longest of its kind.  I, for one, would like to state that our robot overlords should not be made to scale tall cliffs to get out of canyons.
