Underwater robot repopulates damaged Great Barrier Reef

SYDNEY - Scientists are using an undersea robot to repopulate damaged sections of Australia's Great Barrier Reef, according to media reports.

The undersea robot just delivered 100,000 baby corals to the Great Barrier Reef, NBC NEWS reported on Saturday. And researchers hope to develop a fleet of such submersibles to save reefs around the world from rising sea temperature.

The briefcase-size submersible, dubbed LarvalBot, is designed to move autonomously along damaged sections of reef, seeding them with hundreds of thousands of microscopic baby corals.
