Deep-Sea Robot

Underwater Exploration and Resource Recovery Robot – Preliminary Design

Conducted within the M214 design team at Arts et Métiers (ENSAM), this preliminary engineering project aimed to design a submersible robot capable of exploring deep-sea environments and performing light intervention tasks such as sampling and mapping. The study focused on defining the functional architecture, identifying environmental and regulatory constraints, and pre-dimensioning the main structural components.

The project involved competitive analysis (Forssea, Ifremer Ulyx, OpenROV), a detailed functional specification study, and the establishment of a feasible technical architecture integrating propulsion, guidance, and communication systems under 200 m depth conditions.

Key Outcomes

• Architecture definition: Functional breakdown, constraint mapping, and system design methodology (FAST and functional analysis).
• Mechanical sizing: Preliminary strength study of a titanium hull under hydrostatic pressure using Von Mises criterion.
• Environmental integration: Compliance with marine standards (ISO 14040, ISO 16665) and low ecological impact considerations.

This work provided comprehensive exposure to systems engineering, conceptual design, and environmental compliance in harsh marine contexts. It laid the foundation for future simulation, prototyping, and experimental validation phases.
