Robots to celebrate the holiday by cleaning beaches…

July 19th is “Marine Day”, a national holiday here, and what better way to celebrate than to hold the National Coast Clean-up Robot Contest 2010. This year's event is the 13th in an unbroken series of nation-wide robot events.
Based on the 3R's (Reduce, Reuse, and Recycle) the event emphasizes Environmental Education, Manufacturing, and Teamwork. There are two primary classifications:
Marine Rescue Robot, where the robot enters the water and attempts to save a floating doll made of foam.
Coast Disposal Robot, where the robot clears cans, PET bottles, and other litter off a predefined area of the beach. The robot size is limited by the rules so that it has to fit within a cube with equal sides of 1 meter. The robot weight isn't specified, and there is no restriction on the power source, though caution is strongly urged. Apparently during one of the previous competitions a robot using a car battery ran into a potential safety hazard.
