Researchers have been testing for search and rescue operations at the Rentel offshore wind farm in the North Sea. The trials come as the drones are readied for autonomous surveillance, rescue, and detection missions in the near future. The drones also use artificial intelligence to automatically process the images and other data captured during the flights. This will allow many of the jobs currently done by humans to become fully automated, lowering operating costs and response times. The system can also alert a response crew if they are needed.
