Core Concepts
Innovative underwater positioning system for ROVs in confined environments.
Abstract
The content discusses the development of a collaborative aquatic positioning system using multi-beam sonar and depth sensors for underwater robots. The system aims to address the challenges of accurate positioning in confined underwater environments, crucial for inspection, mapping, and autonomous operations. Unlike existing systems, this innovative approach does not rely on fixed infrastructure or environmental tracking, providing reliable navigation in cluttered underwater settings. The proposed system combines an omnidirectional surface vehicle with an ROV to achieve precise localization without additional equipment. Experimental results validate the effectiveness and deployability of the system.
