Abstract
An underwater communication apparatus includes a light transmitting device to transmits a first communication light and a light receiving device to receive a second communication light. Further, a light identification device is used to detect a reference pattern in two dimensions, which is set on a node communication apparatus, to obtain a detection pattern. The light transmitting device and the light receiving device respectively corresponding to the light identification device are set at two relative locations. A power apparatus is used to drive the underwater communication apparatus. A control/monitor apparatus obtains the detection pattern from the light identification device and analyze a difference state between the reference pattern and the detection pattern. According to the difference state, it controls the power apparatus to move the underwater communication apparatus to a location for the detection pattern and the reference pattern being two dimensionally aligned.
