Job offer

At Mines PSL, the candidate will work at the Collège des sciences navales (CSN), a joint laboratory between Mines Paris - PSL and UIMM, located in Sophia-Antipolis and Toulon. In particular, the CSN develops real-time simulators for underwater robots and sensors for pilot training and for training and testing algorithms based on Artificial Intelligence (AI).

What is the topic of the thesis?

The design of underwater drones faces serious engineering challenges and high operating costs restrict testing in real-world conditions. Moreover, the available data for training control or mission planning algorithms generally lack definition and coverage.

To overcome these limitations to innovation, simulators offer a promising avenue, particularly for generating large, realistic synthetic databases. However, currently available simulators either integrate only certain targeted physical models (rather than the entire system) or offer a realistic-looking graphical environment without physical considerations. They are also lacking in models representative of the deep seabed.

This research project aims to contribute to the development of a real-time drone simulator integrating realistic physical models of flow, energy consumption, and sensors (acoustic, visual) within an optimized computing platform. This platform will generate synthetic data for testing or training statistical learning or reinforcement learning algorithms. The work will initially focus on the real-time simulation of acoustic data acquisition (sonar, hydrophone, DVL, USBL) at short ranges (from a kilometer to a few meters) by a moving robot. The modeling will include the relevant physical properties of the elements composing the underwater scene. The simulations will be validated through specific sea trials and the replay of data recorded during oceanographic campaigns.

The project thus highlights the need to take into account the interactions between robot models and the underwater environment, similar to the practices that are developing in terrestrial robotics for the design of control laws and autonomous navigation algorithms.

What will your mission and activities be?

• Conduct a state-of-the-art review of physical and numerical models implemented in real-time simulations of the behavior of underwater robots and underwater sensors, particularly acoustic sensors.

• Model underwater robots, sensors (especially acoustic sensors), and relevant physicochemical properties of underwater scenes, and then integrate these models into a realistic real-time physical simulator. This work will build upon the real-time simulation software components already implemented by the CSN and Ifremer.

• Writing academic papers and participating in national and international conferences.

Eligibility criteria

At Ifremer, the candidate will work within the PRAO team at the Ifremer center in La Seyne-sur-Mer. The PRAO team specializes in Positioning, Robotics, Acoustics, and Optics. It is part of the Underwater Systems Unit and conducts research and development on sensors, processing algorithms, and onboard controllers for the French Oceanographic Fleet's underwater robots. https://www.flotteoceanographique.fr/en/Who-we-are/Direction/Missions-a…, Join Ifremer, an ally of planetary well-being, to gain a better understanding of and better protection for the ocean. From the abyss to the surface, from the coast to the open SEA, Ifremer is the French research institute that is wholly dedicated to the Ocean. Its teams carry out research, innovate and produce expert reports to protect the ocean, exploit its resources in a responsible manner and shares marine data. Ifremer contributes its scientific expertise to throw light on public policies and develops solutions drawn from the ocean to meet the challenges of the ecological transition. Ifremer is the operator of France's oceanographic fleet with its shipbuilding subsidiary Genavir, and imagines, designs and deploys leading edge technological means to solve the ocean's mysteries. Join our teams, made up of 1500 scientists and research support staff, present all along the coastal areas of France and French overseas territories.
