Abstract | Although four-wheel steered mobile robots have less turning ability, compared to two-independent wheeled mobile robots, there is an advantage that they are fit for improvement in the movement speed. Note however that since the wheel slippage is increased due to its advantage, four-wheel steered mobile robots cannot apply a popular dead-reckoning method by using rotary encoders. This paper describes a method for tracking a straight line using four-wheel steered mobile robots by applying an image-based control method, which controls such robots without referring to self positions. A fuzzy controller that is one of model-free controllers is adopted, because a relationship between the movement of a robot and the image that is captured by a camera attached on the robot cannot be modeled easily. The proposed method is evaluated through some simulations and real experiments. |

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.
