Abstract: In this presentation, I explain my ongoing work on designing networked underwater robots. Robots are being developed to automate data collection to monitor coral reef ecosystems. Each robot is equipped with sensors -- Inertial Measurement Unit (IMU), Doppler Velocity Log (DVL), and stereo camera -- for perception/localization in underwater environments, is installed with multiple propellers to make it fully actuated, and communicates with other robots through acoustic communication. I also describe key algorithms being developed -- including a motor controller for underwater maneuvering, Simultaneous Localization And Mapping (SLAM) for sensor fusion/localization, and multi-robot coordination for efficient data collection -- which are crucial for realizing underwater autonomy
