On the 15th and 16th of September 2021, the first tests of the SeaClear robots took place in the Dubrovnik area, Croatia. This was the first time representatives from all the partners met live after the kick-off meeting of the project, due to the on-going pandemic due to CoVID-19.
As we are approaching the final trials for the SEACLEAR system, our team has gathered once again in Marseille from 27 of February until the 3rd of March for further tests. Updated versions of the components were tested alone and in combination with each other, to discover improvement points.
An updated version of the basket was brought on site, featuring AR tags for easier localisation from the Tortuga, fiber brisstles for easier deposit of litter without possibility of escape, and a funnel shaped entry for easier entrance of the Tortuga with the gripper. The new basket was also tested in tandem with its LARS module (Launch And Recovery System) that was developed for the SeaCAT.
Furthermore, the Tortuga was equipped with a refined version of the gripper, which was 3D printed in aluminium to optimize for weight and resistance. Several tests demonstrated that the new gripper can handle litter of different shapes and dimensions, and is ready for deployment for the final demonstrations. Finally, we also managed for the first time to perform real-time localisation of the tortuga using the drone that was flying above.
We are now on the final stretch before our much anticipated demonstrations on Hamburg this June. Stay tuned for updates and details about the project results!
On June 16th and 17th 2020, SeaClear partners participated in a project meeting which was held online due to the situation with the corona virus. SeaClear initiative plans to develop first mixed system of Unmanned Underwater, Surface, and Aerial Vehicles - UUV, USV, UAV - to find and collect litter from the seabed and from the water column. The focus is on coastal areas since that is where waste inflow concentrates. At this meeting, coordinators of each work package provided an overview of the current state of implementation and instructed further tasks in order to comply with the planned schedule of activities. The next meeting is foreseen for September 2020 and should take place in Dubrovnik. Preliminary investigations of the pilot sites in Croatia, namely the island of Lokrum and Bistrina in Mali Ston Bay, has already begun by experts from the University of Dubrovnik. Planned meeting in September will be a great opportunity for other expert partners to also conduct initial demonstrations of currently available systems.
The second round of trials of the SEACLEAR system took place in the port of Hamburg between 10 and 12 of May 2022. The port of Hamburg is the second test site of the project, offering completely different conditions and challenges compared to the first test site in Dubrovnik, Croatia. Underwater visibility is considerably lower, often lower than a few centimetres, while there is heavy traffic present from commercial ships. This makes the use of vision cameras for detecting the litter unusable, with the only reliable detection alternative being sonar sensors.
The event created a significant interest in the local media, and several news outlets visited the test sites to cover and report on our progress. Following the tests and media appearances, we discussed the current progress and future steps until the next meeting in Marseille, in September 2022.
From 12th to 16th of September 2022, the SEACLEAR team gathered at the SubSea Tech headquarters in Marseille for another round of trials and tests. During this meeting, we tested the upgraded components of the system and their interaction. More specifically, a new version of the collection basket was tested with the Tortuga collection UUV, the pose estimation of the mini Tortuga observation UUV was validated online with real data, and we further tested the capabilities of the AUV for detecting litter and the UUVs.

The meeting was a great opportunity to update all the partners on the progress, and discover what are the elements that need to be fine-tuned before the final trials next year. The meeting was also covered by media appearances both in the local and european level.
