About underwater robots and their application in hyperbaric welding

The seabeds remain largely mysterious. However, their exploration and exploitation con-stitute major stakes for the future of our planet. The exploitation of their natural resources (fisheries and biological resources, minerals, oil and gas) and the study of their influence on the climate are unavoidable challenges if we want to offer a future to future generations. Advances in underwater robotics make it possible to envisage better knowledge and exploi-tation of this environment still inaccessible to humans. This article presents the current state of technology in underwater robotics, its civilian applications (current and affordable in the near future) mainly for autonomous and hyperbaric welding robots.
