Intelligent deep sea robotics: Autonomous underwater robot with intelligent 3D cameras for high precision search and tracking in deep seas

Okayama University researchers in collaboration with industrial partners have developed an innovative underwater robot incorporating intelligent three-dimensional object recognition CCD technology for autonomous search and tracking operations over long durations of time in open water.

“Our Autonomous Underwater Vehicle (AUV) operates using the combination of our new ‘Move on Sensing’ (MOV) three dimensional visual servo CCD technology with real-time stereopsis and detection of conventional sonar signals,” explains Mamoru Minami, professor at the Graduate School of Natural Science and Technology, Okayama University. “Underwater navigation with this combination of sound and 3-D visual servo feedback enables our AUV to search, track, and pinpoint targets with a precision of 5 mm. We expect this accuracy to improve this figure to 0.5 mm, which we have obtained using ground based robots.”

The Okayama University MOS/AUV is expected to find applications in areas including decontamination of radiation contaminated the floors of seas, oceans and lakes; exploration of ocean floors for materials such as methane hydrate and rare earth metals; maintenance of underwater telecommunications cables; environmental monitoring and surveys of marine life; underwater mines; recovering space debris; and lifesaving.
