Abstract: The study and use of underwater robot is of significant importance for sea exploration. With the development of sea exploration, the Autonomous Underwater Vehicle(AUV)are becoming a new focus of study. To solve the problem of low communication rate and the problem of real-time for AUV in deep sea exploration, we propose a scheme for "an intelligent perceptive system based on distributed information fusion for underwater robot", and explain the process of the system to solve practical problems using the instance of conch-snatch.
