Diesel-powered AUV

14/02/2008

The Dorado vehicle is capable of towing a sonar towfish at speeds up to 12 knots and depths to 200 meters. It is powered by a 315 kW marine diesel engine. Air is drawn through the mast and exhausted through the stabilizer above the contra-rotating propeller. The towfish is developed to follow the seabed at low altitudes and is fitted with a multibeam side scan sonar.

A vehicle that looked much like this was first built and used for hydrographic surveys (on a test Basis) in the 1970's out of Bedford Institute of Oceanography in Halifax. I believe the chief proponent for this unit was a Dr. Gilbert. After 30 odd years we how have a working unit.

Demo of RIEGL Airborne Bathy Scanner in Camcopter UAV

It's not an AUV but an UAV. So an unmanned vehicle, but in the air instead of underwater. This movie shows a demonstration of the bathymetric laser scanning capabilities of the RIEGL VQ-820-GU hydrographic airborne sensor in reality. For more information on the technical side, please see the news release on Hydro International.
