| Abstract | Autonomous mobile robots navigation and control systems are still hugely important in real time robotic applications. When moving towards fully autonomous navigation, guidance plays a vital task for successful autonomous navigation. In this paper, the authors propose real time guidance fuzzy logic application based on edge and color information surrounding the road surface by using omnidirectional cameras. Autonomous navigation systems must be able to recognize feature descriptors from both edge and color information. Firstly, it was proposed to extract the longest segments of lines from the above mentioned methods. Secondly, RANdom SAmple Consensus (RANSAC) curve fitting method was implemented for detecting the best curve fitting given the data set of points for each line segment. Thirdly, the set of intersection points for each pair of curves were extracted. Fourthly, the Density-based spatial clustering of applications with noise (DBSCAN) method was used in estimating the vanishing point (VP). Finally, to control the mobile robot in an unknown environment, a fuzzy logic controller facilitated by the VP was implemented. Preliminary results were gathered and tested on a group of consecutive frames undertaken at the University of Ulsan (UoU) to prove their effectiveness. |

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.
