Underwater Robot Technology and Future Trend Analysis

Abstract

Underwater positioning and navigation is a technology that provides the attitude, speed, position and other information of underwater robots. It is the premise for underwater robots to successfully complete various underwater tasks. The underwater environment is complex and changeable, and a single positioning and navigation technology will inevitably not meet the needs of long-range, multi-target and high-precision. The navigation system of the future underwater intelligent robot integrates the integrated navigation mode of various technologies. This paper discusses the basic underwater positioning and navigation mode and integrated navigation mode, describes the development process of underwater positioning and navigation technology, compares the research methods and progress of Chinese and foreign scholars, analyzes the current research bottlenecks and technical difficulties, and points out the direction for future research, which can be used as a reference for the follow-up research of underwater robot positioning and navigation system.
