| Abstract | PVDF sensors are used to measure the dynamic pressure surrounding a biomimetic autonomous underwater vehicle (BAUV). To track the motion of a periodically oscillating source by following the pressure generated by the source motion, the BAUV estimates pressure derived by its own, and subtract those information to find the signals of the source motion. Mechanics and motion control of the BAUV is derived. The BAUV's tail fin is then controlled to be an oscillator like mechanism. A dipole model is used to predict the dynamic pressure around the tail fin using the potential flow theory. A moving dipole source is then considered as an external source that is oscillating with constant amplitude and frequency. Relative phases between the tail fin and the dipole source are estimated using measurement from the PVDF sensor attached on the robot's body. Coupling forces based on the phase angle between the tail and the oscillating source are derived to drive the tail fin. Tank experiments employing a captured BAUV model beside a moving dipole mechanism are conducted to observe the phase following performance. The future application of this paper is directed to the control a group of fish robots. |

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.
