17 Aramis Project Advanced ROV package for Automatic Mobile Inspection of Sediments a scientific and technological system to be integrated with typical mid-class existing ROVs to carry out pelagic and benthic investigations both in shallow and deep waters. The ARAMIS system capabilities have been demonstrated by operating the system with IFREMER Victor 6000 and CNR-IAN Romeo.

18 Romeo-ARAMIS Trials in the Aegean Sea (Milos) Final demo:16-28 September 2000 Aramis Test Trials in Crete and Milos (Greece) were undertaken on the hydrothermal vent areas of the island.

19 IX Expedition Roby2 performed 18 dives, maximum depth of 150 m. Verification of requirements and constraints of SARA (Sottomarino Autonomo Robotizzato Antartico) Ecology and Biogeochemistry of the Southern Ocean: survey of the Marine Antarctic Specially Protected Area nearby Terra Nova Bay station

20 XIII Expedition Romeo performed 75 dives, for a total mission time of 120 hours at a maximum depth of 320 m. 1st Leg (1st November - 4th December 1997)» Project 2.b.3 Ecology and Biogeochemistry of the Southern Ocean. Romeo was operated through a hole in the pack and carried a scientific payload for the plankton sampling, the measurement of pack luminance and the characterisation of water chemical and physical properties. It performed horizontal traverses at a constant speed of 25 cm/s and depth of 3 to 10 m. 2nd Leg (5th December th January 1998)» Project 4a Robotics and Tele-science in Extreme Environment. Three ice camps were set up to operate Romeo for the testing of acoustic navigation devices and algorithms. 3rd Leg (10th January - 16th February 1998)» Project 2.b.3 Ecology and Biogeochemistry of the Southern Ocean. Romeo was operated from the boat Malippo to perform surveys and to take pictures and water samples in the Marine Antarctic Specially Protected Area of Terra Nova Bay.

33 Bilateral agreement Italy-Portugal 1999 Lisbon-Genoa Experiment CNR-Istituto Automazione Navale IST-Instituto de Sistemas e Robotica The June 21st 1999, Romeo's automatic guidance system was driven via Internet by the mission control system located in Lisbon to execute in the Genoa pool a mission pre-defined by the Portuguese user. The link between Romeo and the Internet has been ensured trough a cellular GSM phone empowered for data transmission. The Portuguese scientists could follow in real-time the development of the mission through a virtual representation of the vehicle's telemetry.

34 Web interfaces for underwater virtual environments CNR Agenzia Progetto Giovani developing a web interface capable of allowing remote users to interact with a robotised vehicle in an underwater virtual environment by planning missions and observing the vehicle's performances.
