Abstract
A manipulator apparatus carried by a remotely operated vehicle is provided with a suction device capable of gripping underwater objects. The suction portion of the manipulator apparatus utilizes suction chambers isolated from the body of water. When fluid is removed from the suction chambers an appropriately shaped moveable wall moves inwardly thereby forming a suction cavity between the suction device and the object to be moved. The moveable wall may take the form of a rubber-like flexible membrane wall or a piston moveable within the suction portion of the manipulator apparatus.
