climbed out of the Grand Canyon and walked 500km from Tokyo to Kyoto, but apparently neither was enough to prove it and its namesake batteries' true mettle. This time, Panasonic's putting three of the robots through the Ironman Triathlon in Hawaii, and they've got a week to swim 2.4 miles, bike 112, and run a 26.2 mile marathon. Unlike the meatbags running the race who have a day to finish, the robots get a week -- though they'll be doing their thing 24 hours a day while only taking breaks to recharge their three AA batteries. Intrigued? The race starts on October 23rd, so there's plenty of time to watch the appropriately dramatic video explaining the challenge facing the triumvirate of tiny triathletes after the break.
