Autonomous Robot Fleets Target Seabed Litter in EU Cleanup Initiative

• EU-funded initiative SeaClear2.0 uses autonomous robot fleets to identify and collect litter from the seabed.
• The technology aims to replace dangerous and expensive manual diving operations while preventing plastic waste from degrading into microplastics.
• Robots are trained to distinguish debris like tyres and metal from marine life using AI, sonar, and camera imagery.

Technology and Operations

• The system deploys unmanned surface vessels that release aerial and underwater detection drones to map the sea floor.
• Retrieval is performed by collection drones or smart grippers attached to surface-vessel cranes.
• Additional components include autonomous barges that act as floating bins to transport collected waste to shore.
• The system is designed to operate in adverse weather and low-visibility conditions where human divers struggle.

Project Evolution and Challenges

• Developed from the original 2020–2023 SeaClear project, SeaClear2.0 includes 13 partners from across Europe.
• Initial trials in Hamburg highlighted lifting challenges, such as 200kg tyres, leading to successful hardware redesigns demonstrated in Marseille.
• Future testing is scheduled for Venice, Dubrovnik, and Tarragona to refine the system.

Potential Applications

• While focused on litter, developers are exploring the technology for:
  • Detecting unexploded World War II mines on the seafloor.
  • Harbor security and monitoring for illegal or dangerous activities.
• The project aims for a finalized, streamlined version by late 2026 for use by local authorities.
