How a Fleet of Specialized Robots is Battling Ocean Plastic Pollution

The monumental crisis of plastic pollution in our oceans, with millions of tons littering the seafloor, is being met with a high-tech solution: a coordinated fleet of autonomous robots. The international SeaClear2.0 project is pioneering this innovative approach to tackle waste in hard-to-reach marine environments.

This project, active from 2023 through 2026, utilizes a team of six robots, each with a specialized role in locating, collecting, and removing plastic debris.

The Robotic Fleet: A Coordinated Clean-Up Crew

The system operates with a multi-layered strategy:

• Aerial Surveillance: A SeaHawk drone flies overhead to identify large concentrations of litter from the sky.

• Surface Coordination: Three unmanned surface vehicles (USVs) manage the operation. The SeaCAT acts as the mission’s communication hub. The SeaDragon docks with the SeaCAT to transport collected waste to shore, while the SeaBee uses a net towed between two mini-robots to capture floating debris.

• Underwater Collection: Below the surface, the Smart Grapple autonomously collects litter from the seafloor. Meanwhile, a Mini TORTUGA robot maps the seabed to pinpoint pollution hotspots.

A Holistic Strategy for a Global Problem

SeaClear2.0 goes beyond simple collection. The project holds workshops in heavily polluted areas, like Marseille, France, to understand local challenges—from poor waste management to vandalism—and develop targeted solutions. This includes advocating for policy changes and improved city infrastructure to stop plastic at its source.

By combining cutting-edge robotics with community engagement and policy work, SeaClear2.0 represents a comprehensive and promising mission to restore the health of our oceans.
