Project CETI uses AI and robotics to track down sperm whales
- Project CETI uses robotics and artificial intelligence to decode the vocalizing of sperm whales in the New England Coast.
- Researchers from Cetacean Translation Initiative can spend hours searching for an elusive sperm whale to surface.
- Project CETI aims to decode sperm whale vocalizations with their Autonomous Vehicles for Whale Tracking And Rendezvous by Remote Sensing (AVATARS) framework.
- The AVATARS framework is the first co-development of VHF sensing and reinforcement learning decision-making for maximizing the rendezvous of robots and whales at sea.
- This new study involved sensing devices such as Project CETI aerial drones that use VHF signals for estimating the direction of pings from CETI’s on-whale tags.
- With one of the widest global distribution of any marine mammal species, sperm whales are difficult to track down and learn from.
- Once the Project CETI researchers can track down the whales, they must gather as much information as possible during the short windows of time they spend on the surface.
- The research team tested the AVATARS framework in a controlled environment with devices that mimic whale behaviors and then in the real world.
- The team must try to gather data without disturbing wildlife and work mostly with drones and specially developed tags that latch onto whales and collect data.
- Outside of Project CETI, AVATARS can be utilized to protect sperm whales and other sea mammals in their natural environment. It could also be used to reroute ships away from sperm whale hotspots.
