Abrégé

The invention relates to an autonomous underwater drone (1) and to a method for manufacturing such an autonomous underwater drone (1) comprising a step of assembling a body (2) comprising at least a battery (3) and an electronic device (4) powered by the battery (3), a step of inserting the body (2) into a mould comprising two mould cavities, a moulding cavity being formed between the two mould cavities and the body (2). The method also comprises a step of overmoulding the body (2) in which the moulding cavity is filled with a liquid polymer material, a demoulding step carried out after curing the polymer material in order to obtain an autonomous underwater drone (1) comprising a hull (8) overmoulded around the body (2), and a step of mounting at least one thruster (25a, 25b, 25c, 25d) on the hull (8).

Abrégé

The present invention relates to a buoying device, to a system for exploring a submerged area, and to methods for deploying and collapsing such a buoying device. The buoying device is characterized in that the buoy (1) includes a sound-emitting/receiving means and a propulsion means (11) configured so as to enable the navigation thereof parallel to the water surface (14) and/or contribute to the buoy rising back up to the surface (14). The method for deploying a buoying device for a submerged area (7) includes: a step of indicating a predetermined geographic flow position to the buoy (1); a step of navigating the buoy (1) from the instantaneous geographic position thereof to the predetermined geographic flow position; and a step of submerging the buoy (1) in the submerged area (7). The invention can be used in the exploration of submerged areas, e.g. for archaeological research, the study and tracking of marine flora and fauna, and oil, gas, or mineral exploration.
