| Abstract | In this paper, we propose an autonomous navigation system in urban environments. In order to create a useful navigation system in urban environments, the system examines whether the area near around is traversable or not in real time, instead of using prior knowledge of dense maps. To examine the traversability robustly, the system adopts the following technologies. The system involves a localization with the information of GPS and dead reckoning, and integration method using Divided Difference Filter (DDF). DDF is an appropriate localization method using truncated data of GPS in urban areas. The system also estimates traversability of road regions using a laser range finder (LRF). By estimating traversability, robot is able to run safely on the route even if localization had poor accuracy. Lastly, the system detects moving obstacles using LRF, because the robot must be operated in environments where many people would exist. The effectiveness of the proposed system is proved through some experiments in outdoor environments including various situations. |

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.
