Panasonic sure knows how to promote their EVOLTA brand of rechargeable batteries: first, a cute mini robot powered by the batteries hoisted itself up a 500 meter-cliff at Grand Canyon, then an EVOLTA robot took on the Le Mans 24 circuit in France, before traveling 500KM from Tokyo to Kyoto last year. And now Panasonic announced [JP] plans to let the little guy start at the Ironman Triathlon in Hawaii on October 24 (the company is to launch a line of improved EVOLTA batteries next month). In other words, the robot is supposed to swim 2.4 miles, ride a bike for 112 miles before running a marathon (26.2 miles) - all powered by EVOLTA batteries.
