| Abstract | Wireless capsule endoscopy recently demonstrated its potential as leading technology for gastrointestinal tract examinations. Many research groups are focusing their efforts on the design of active locomotion methods to allow a complete maneuverability of the device along the gastrointestinal tract. A promising approach for locomotion is represented by master-slave magnetic coupling; however the typical large gradients of magnetic forces make device controllability very hard with important safety concerns: in this framework magnetic capsule localization and interaction force control become extremely relevant. In the present work, a preliminary on-line localization has been implemented obtaining a position feedback closed loop control of a magnetic driven capsule endoscope. Furthermore, interaction forces with the environment have been evaluated by exploiting a dedicated setup for magnetic dragging. Distributed charges-current and dipole-dipole magnetic models applied to capsule endoscopy have been investigated and results have been compared with experimentally measured magnetic forces. Advantages and limitations of employed models have been evaluated and their usability for Real-Time force calculation has been discussed. |

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.
