Abstract | This paper develops methodologies and technologies for ultrasonic self-localization of an autonomous mobile robot (AMR) using a fuzzy adaptive extended information filtering scheme. A novel ultrasonic localization system consisting of two ultrasonic transmitters and three receivers, is presented to estimate both the static and dynamic position and orientation of the AMR. A fuzzy adaptive extended information filter (FAEIF) is presented to improve estimation accuracy and robustness for the proposed localization system, while the system lacks of sufficient information of complete models of the process and measurement noise varies with time. A static pose estimation utilizing the averaging approach is investigated as well. Six time-of-flight ultrasonic measurements together with the vehicle's dead-reckoned location information are merged to update the vehicle's dead-reckoned location information are merged to update the vehicle's pose by utilizing FAEIF sensor fusion algorithm. The proposed algorithm were implemented using an industrial personal computer with a computation speed of 800 MHz, and standard C++ programming techniques. The system prototype together with computer simulations and experimental results has been used to confirm that the system not only provides precise estimation of both the static and dynamic pose of the AMR, but also provides a simpler and more economical structure for navigation use and installation/calibration. |

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.
