Robot climbs 1640-foot cliff at Grand Canyon
May 26, 2008 Panasonic have sent a 17-centimeter tall, 130-gram robot up a 1738 foot (530m) length of rope suspended next to a 1640 foot (500m) cliff at the Grand Canyon. The PR stunt was designed 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. Powered by two Evoltas, the robot reached the top after 6 hours and 45 minutes.
