There is a large group of robotics research staff in Shenyang Institute of Automation, Chinese Academy of Sciences, with a State Key Laboratory of Robotics. Unmanned marine vehicle (UMV) is one important part of our research areas. Over the past 30 years, we laid a solid foundation through carrying out research independently, and sought international cooperation to improve the level of basic research and minimize weaknesses, and thus realize indigenous innovation. Many firsts have been created in the history of marine vehicle development of China, which make us the leader in the domestic academic field and acquire popularity abroad. This paper provides a brief review on the SIA’s research evolution in the field of UMV for the past 30 years and prospects for the future development.
