| Abstract | Sensor fusion and sensor integration is becoming an increasingly popular approach in dealing with complex sensor systems in autonomous mobile robots (AMR). However, the procedure for the sensor integration and sensor fusion is a non-trivial process. This paper presents a scenario based approach to sensor fusion based on the autonomous evolution of sensory and actuator driver layers through environmental constraints (AEDEC) [T.A Choi, 2002]. Using the scenario based approach, the programmer's work of creating a sensory driver will be eliminated by having the AMR learn the driver on its own. In the process of creating each scenario, sensor fusion is automatically implemented. If sensors change or even if the sensor configuration changes, the driver can be updated by having the AMR relearn the driver over again. Due to the tabular structure of the scenario based sensory drivers, malfunctioning sensors can not only be detected, but the driver can automatically adapt to the malfunctioning sensor in real-time. Furthermore, different AMR's trained using AEDEC architecture will have similar interpretations of its environment. This is guaranteed by having the AMR learn the driver in the same highly structured training environment. The behavioral coding is simplified by eliminating any reference to hardware dependent parameters. Finally, the level of abstraction and the consistency of the highly structured environment allows for coding portability. |

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.
