Épaulard is a Frenchremotely operated underwater vehicle of theIfremer. She was the first robotic submarine capable of taking photographs at a depth of 6000 metres. Built in 1980,Épaulard was decommissioned in 1991.
Épaulard was designed and built byECA Group[1] She was teleoperated from a support ship by means of acoustic signals.[2] While the submarine herself displaced three tonnes, the entire system would use up 35m² of deck space and weight 20 tonnes; such systems were installed on a number of Ifremer ships such asNoroît,Suroît,Atalante orJean Charcot.[2]
In 1983, she was upgraded with a vertical propeller and a remote TV system with acoustic broadcast of images.[2]
