HATSUKAICHI, Hiroshima Prefecture--Neither a tangle of algae nor the sea could drain the life out of Panasonic Corp.’s record-seeking Mr. Evolta Neo robot.

The battery-operated humanoid completed the 3-kilometer swim here at Itsukushimajinja shrine, a World Heritage site, on the island of Itsukushima on Nov. 10.

The 17-centimeter Mr. Evolta Neo, powered by two of the company's AA-size batteries, was recognized by Guinness World Records for the world’s longest distance swam by a dry cell battery-operated robot.

Mr. Evolta Neo rode face-down on his wooden surfboard from the opposite shore of the island and headed toward Itsukushimajinja shrine.

Right after the start, it became entangled in algae. But the robot broke free and propelled itself forward by rotating its arms and reached the goal, taking three hours and 22 minutes.

Since 2008, the electronics company has held similar events by robots to promote the efficiency of its batteries.

The robot also set a Guinness World Record in 2009 by completing a 24-hour endurance run at a circuit in France. The Itsukushima swim is the fourth time for it to be recognized as a Guinness World Record holder.
