Enabling Long-Term Deployments of Underwater Robotic Platforms in Remote Oceanic Locations

The objective of this project is to develop and demonstrate a cost effective solution for recharging autonomous underwater vehicles used in remote oceanic areas, including deep-sea deployments. The ultimate objective is to support the collection of marine environment and human activities data for long-periods of time.

The ENDURE implementation approach is underpinned in three main components:

  • docking maneuver, based on a novel vision based AUV positioning subsystem;
  • wireless battery recharging subsystem, capable of tolerating misalignments;
  • Wi-Fi based high-bandwidth short range communication subsystem, for fast data downloading.

The proposed solution consists in having the underwater charging station (UCS) moored to the seabed and also connected to a surface platform that generates energy. This architecture allows for a significant reduction of the impact of surface waves on the movement of the UCS. Offshore conditions imply the use of a self-sustaining platform, capable of energy production. The platform will be able to generate energy for recharging all underwater smart platforms, as well as, receiving the collected data and transmitting it to shore.
