| Abstract | This paper proposes a path-planning and guidance method of an autonomous underwater vehicle (AUV) to perform detailed inspection of underwater structures. The targets are support legs of on-water platforms consisting of cylindrical rods. Underwater inspection of such kind of structures is important for maintenance, security and environmental assessment. Autonomous underwater vehicles (AUVs) have a potential to make these tasks more inexpensive and reliable, compared with conventional methods. The path-planning method generates a set of waypoints for an AUV to follow the surface of the target with a constant distance, based on the pre-given information about the configurations of both the target and the vehicle. The guidance method actually controls the vehicle to follow the waypoints, assuming the position and attitude of the vehicle is precisely estimated in real-time. By combining these methods with the localization method we had proposed [1], an AUV can perform fully autonomous observation of underwater structures if only their configuration is known. The performance of the proposed method was verified though tank experiments using the AUV Tri-Dog 1. A simple model of a jacket was installed in a test tank and the vehicle succeeded in observing the target. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
