The Little Yellow Submarine Saving Our Reef

In a world-first, the RangerBot will kill off toxic starfish damaging the reef

Aussie researchers have developed a killer robot to counter the damage being done to the Great Barrier Reef by the destructive crown-of-thorns starfish, which feasts upon the reef's coral.

According to the ABC, a collaboration between Queensland University of Technology researchers, Google, and the Great Barrier Reef Foundation has created a small yellow robot called RangerBot that will dive down into the reef and administer a lethal injection to the starfish.

The robot will be able to swim around for eight-hours on one battery charge, and it will be able to reach spots too difficult for divers.

“RangerBot has the potential to revolutionise the way we manage our oceans and is an important tool to have at our disposal in the quest to save our coral reefs,” Foundation managing director Anna Marsden told the ABC.

One of the researchers said the robot has so far proven to be 99.4 per cent accurate in its delivery of the lethal injection.

However, it will not only be destroying the toxic starfish, it will also be monitoring and collecting data about coral bleaching, water quality and pollution.

Researchers said the robot might soon be used in coral reefs around the world.
