Evolta Robot, powered by 2 double A Panasonic batteries, climbs 530 meters up a rope at Grand Canyon. Why is this cool? Well it’s cool that a 17 centimeter tall can do so much with just 2 double A batteries plus it’s a great viral marketing for Panasonic batteries.  Looks like Duracell battery and Energizer bunny have their paws full… On May 24, a 17-centimeter tall, 130-gram Panasonic Evolta battery mascot robot scaled a 500-meter cliff at the Grand Canyon in a publicity stunt to showcase the endurance of the Evolta AA alkaline battery, which the Guinness Book of World Records recently recognized as the longest-lasting of its kind.
