Present State and Tendency of Bionic Underwater Robot

Because of high flexibility and intelligence, bionic underwater robots have become one of the focuses of robotics in recent years. According to the locomotion method of imitating underwater creatures, bionic underwater robot can be classified into three classes: fish robot, walking underwater robot and worming underwater robot. The main characteristics of the typical robots of each class are described in this paper. With the development of science and technology, bionic underwater robot will be improved in driving system made-up by smart materials and locomotion theories gradually, individual intelligence and team cooperation.
