This video presents some personal experimental results from the Submeeting event held from 27 to 31 May 2024 at St Raphel in south-east France. The experiments in this video follow on from the previous video on the drone & cap event. The aim of these experiments is to control two ROVs to place them in a stable formation, knowing that their position is only measured every 9 seconds using a USBL ...

The RUR project aims to design, develop and build an underwater drone with reconfigurable vector propulsion which can evolve in a fleet so as to be able to carry out complex missions autonomously. Despite progress, AUVs still suffer from reduced maneuverability. Better agility would provide increased autonomy and make it possible to respond to a wider range of missions. It is also becoming nece...

By Loïca Avanthey and Laurent Beaudoin Description of the flexible micro-geodesic networks set up during the 2022 edition of the Submeeting to serve as ground truth and of the acquisitions made which made it possible to publish an open dataset. Explanation of the need to collect information for the establishment of the ground truth networks for the 2024 edition of the Submeeting

As the exploration and monitoring of underwater environments grows in importance for science, industry and conservation, underwater robotics is positioning itself as a key sector in research and development. Simulators provide an essential platform for testing, refining and confirming underwater robotic technologies in a simulated setting before their application in realworld conditions. This p...

Improving 3D reconstruction in the submerged world is a fascinating challenge that combines technological innovation and scientific understanding. In this brief presentation the motivation and need of underwater 3D reconstruction will be established under the scope of archaeological excavation in Mazotos shipwreck site. The challenges that underwater environment poses, the inherent restrictions...

By Erica Nocerino and Fabio Menna In this presentation, we will give an overview of our research efforts over the last decade targeted on bridging specific aspects of sister optical-based techniques, i.e. photogrammetry, computer vision and robotics, aimed at mapping and monitoring the underwater environment. The driving focus has been to integrate the rigorousness of photogrammetric methods ai...

Work on autonomy in robotics often focuses on the low-level functional layer (hardware reliability, resilience of sensor data, etc.) or the high-level decision-making layer (navigation algorithm, planning, fault management, etc.). However, there is a little explored in-between, the executive layer, which must provide behaviors that can be used by the decision-making layer based on the elements ...

The fundamental objective is to provide future underwater robots with motor adaptation capabilities to their task and their environment in order to carry out complex inspection and maintenance tasks of submerged MRE (Marine Renewable Energy) structures. These tasks require the autonomous robot (AUV) to move in a precise manner, possibly following predetermined trajectories, in order to avoid co...

The Oceans Systems Laboratory at Heriot-Watt University has been involved in underwater robotics research for many years. We initially focused on vehicle design but since the early 2000 we have dedicated ourselves to advancing autonomy. We have developed methods for underwater exploration using AUVs and ROVs using live sensor processing to understand the environment and adapt the mission to kee...

Since 2016, the Cosmer has been involved in robotics activities mainly focused on cable management. The concept of robot chain was introduced to deal with the exploration of confined environments. First, local perception of the cable that link two robots was investigated to estimate the shape of the cable. To this end, the catenary model was used for weighted cables. Then, the shape of the cabl...

Underwater cameras operate directly in a scattering medium. Hence, computer vision algorithms are posed with unique challenges: (i) the refraction of light entails geometric distortions when the optical interfaces air glass-water are traversed by the light rays and (ii) the images are adiometrically distorted due to depth-dependent attenuation and scattering effects. Such effects can be precise...

La modélisation 3D est un outil d’avenir pour la découverte, la valorisation et la protection du milieu marin que nous admirons tous en tant que professionnels de la mer ou citoyens engagés. SEMANTIC TS a créé la première plateforme dédiée à la modélisation haute résolution des fonds marins côtiers en 3D de Méditerranée française. Cette initiative touche directement les acteurs des activités su...

La Méditerranée n’est pas, comme son surnom de « Grande Bleue » pourrait le suggérer, une longue mer tranquille. Si la circulation générale des masses d’eau est bien connue (en sens anti-horaire dans les 2 bassins), ce n’est qu’à l’échelle de l’année. En effet à un instant t un océanographe ne pourra pas dire dans quel sens va le courant sans une information essentielle (d’origine satellitale):...
