Safran sea trials: Full mission Execution with ECHO2

Period: October 2014

Location: Orosei, Sardinia, Italy

This video is part of the Spicerack  project and shows the execution of a complete reference mission with the latest generation of the Safran vehicle, ECHO2, in a 2kg negative buoyant configuration. After its deployment, the vehicle dives for its weight and starts execuitng the mission when detects to be at the starting depth. Then all the mission steps are carried out until the ending phase, when the AUV takes off and starts navigating back to surface. 

Safran sea trials: Full Mission Execution

Period: August 2014

Location: Orosei, Sardinia, Italy

This video is part of the Spicerack  project and shows the execution of a complete reference mission. After its deployment from the supporting rubber boat, the vehicle reaches the target point and land on the seabed. A burying phase is then operated for having a better coupling with the seafloor and a higher resistance to current disturbances. The video terminates after the de-burying phase when the AUV takes off and starts navigating back to surface. 

Trident Project Final Demo

Period: September 2012

Location: Mallorca, Spain

This video shows the activities carried out at the final demo of the Trident project. After the last summer school, field trials were performed for showing the main achievements obtained during the project. Preliminary tests were related to cooperative navigation. Then a test on the intervention capability is shown with the i-AUV autonomously reaching, grasping and recovering a black box located on the sea-bed.

Trident Project: Integration Tests

Period: May 2012

Location: Girona, Spain

This video shows the operations related with the arm-hand integration within the Trident project. After the two mechatronic subsystems, developed by Graal Tech and the University of Bologna, were assembled together, a test in the pool was executed for assessing the proper functioning of the robot, making it reach and grasp a black-box located on the floor.

Folaga Maneuvrability Tests

Period: April 2010

Location: Genova, Italy

This video shows the enhanced maneuvrability of Folaga, making it a hybrid vehicle, with hovering capabilities. The AUV performs vertical and horizontal translations, and horizontal rotation and variations of the pitch angle on the spot. In addition the AUV exhibits its capability of gently landing on the seabed and successively taking off from it.

Folaga Glider Mode Test

Period: April 2010

Location: Genova, Italy

In this video Folaga is shown while navigating in low-power glider mode. By periodically changing its buoyancy and the pitch angle, the vehicle alternates downward and upward motion phases. Two wings, properly attached to the hull, increase the hydrodynamic lift. making the vehicle moving on diagonal paths without using propulsion. 

EWM test in ESA pool

Period: September 2007

Location Cologne, Germany

This accelerated video was realized in the ESA facility in Cologne and shows the robot walking on a mock-up with hand-rails. At the end of the video man-robot interaction is shown, when the "ARM" manipulator is used for giving a tool to a diver.

EWM simulated walk on hand-rail

Period: May 2006

Location: Genova, Italy

This simulation was realized for verifying the effectiveness of the developed control algorithms, enabling the robot to walk on the hand-rail by alternatively grasping and releasing it with two manipulators.

The main peculiarity of the adopted strategy was the idea of managing the redundancy of the system (14 d.o.f. moving at the same time) for preserving its safety against risks of self-collisions.
