Earth’s oceans and waterways face threats from climate change, pollution, and invasive species. To protect these environments, we need reliable ways to monitor their health. This project introduces a bionic sea turtle robot, inspired by green sea turtles, to help survey ecosystems with minimal disruption to aquatic life. The robot was designed with a custom propulsion mechanism and optimized using computer simulations and pool testing. It can navigate autonomously at various depths, following a set path using onboard sensors and control algorithms. An AI-powered computer vision system was developed, capable of detecting coral bleaching with 96% accuracy. This nature-inspired robot demonstrates how biomimicry and advanced technology can support marine conservation and ecological research.
