Flying underwater imager with multi-mode operation for locating and approaching underwater objects for imaging

摘要

A flying underwater imager device operates in two modes, a tow mode and a free fly mode. In the tow mode for locating underwater objects, the imager device opens foldable wings for remaining depressed below the surface when the wings generate a negative buoyancy. Otherwise, neutral buoyancy characteristics bring the imager device back to surface. In the free fly mode for approaching and imaging underwater objects, the imager device closes the foldable wings and uses thrusters for moving into position to image the underwater objects.
