| Abstract | Water pipelines are an important part of our social infrastructure. Early failure detection of the pipelines will help to prevent breakdown and avoid the large cost involved if a accident occurs. As pipelines are enclosed environments and difficult to access, pipeline inspection robots are increasingly used for routine inspection and early failure detection. In our research we propose the use of a small untethered AUV for the visual inspection of the pipeline interior. The vehicle carries optical sensors to aid non-contact motion inside the pipeline and also to capture images of the pipeline interior. The vehicle has identical front and rear sections and has a pair of cone laser and fish eye camera on either ends. The cone lasers and cameras act as range sensors as well as payload to capture pipe line interior images. A realtime vision based control system was developed for the autonomous operation of the proposed vehicle inside pipelines. A new offline position estimation algorithm estimates lateral position and pose of the vehicle inside pipeline. Laboratory experiments were performed in a test pipeline without and with water flow. The results of the experiment show that the proposed technique is efficient for non-contact inspection of a pipeline and helps to make vehicle compact to navigate through the enclosed environment inside pipelines. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
