Underwater robots kill invasive fish to save the oceans

Autonomous underwater vehicles identify and kill invasive starfish at the Great Barrier Reef in Australia. Robots can help undo some of the damage that has been done to our environment. Unmanned aerial vehicles are already being used to track endangered wildlife and assist land conservation efforts by mapping ecosystems and monitoring protected areas. Meanwhile at sea, autonomous sailing drones are monitoring ocean water to detect any pollution and track changes in temperature and pH. Now, underwater robots are also working to restore biodiversity by hunting invasive species.
