Remotely Operated, Underwater Robot Will Assist in Marine Research

An underwater robot made a splash at a University of Delaware swimming pool recently in a test of the new equipment, which will soon be used in field research. Douglas Miller and Arthur Trembanis, associate professors of oceanography, tested the device's maneuverability and imaging features. The robot, called a remotely operated vehicle (ROV), has four waterproof video cameras, a sonar system which uses sound to make detailed pictures of seafloor contours, and a three-pronged arm opens and closes to grip marine samples. Sensors on the ROV record depth, date, and time with each video stream.
