An autonomous starfish-killing robot is close to being ready for trials on the Great Barrier Reef, researchers say.
Crown-of-thorns starfish have have been described as a significant threat to coral.
The Cotsbot robot, which has a vision system, is designed to seek out starfish and give them a lethal injection.
After it eradicates the bulk of starfish in a given area, human divers can move in and mop up the survivors.
Field trials of the robot have begun in Moreton Bay in Brisbane to refine its navigation system, Queensland University of of Technology researcher Matthew Dunbabin told the BBC.
