How Project CETI uses drones to humanely tag sperm whales - The Robot Report

Project CETI (Cetacean Translation Initiative) has been developing innovative methods since 2020 to humanely tag sperm whales using robotics and AI, with the ultimate goal of decoding their vocalizations. Traditional tagging methods involve approaching whales by boat and using long poles, which is logistically difficult and invasive. Instead, Project CETI employs modified first-person view (FPV) racing drones that are waterproofed and equipped with custom interfaces to deploy biologically-inspired suction-cup tags on whales. These tags collect critical data such as bioacoustics, heart rate, dive depth, and body orientation. The drones’ maneuverability, speed, and relatively low cost make them well-suited for tagging whales during their brief surface intervals, which last only about eight to ten minutes. The project faces challenges in timing the drone deployment precisely due to the whales’ unpredictable surfacing and the dynamic ocean environment. Skilled operators remotely control the drones, achieving an average deployment time of about 1 minute and 15 seconds
