| Abstract | Research in mobile robotics, unmanned systems, and autonomous man-portable vehicles has grown rapidly over the last decade. This push has taken the problems of robot cognition and behavioral control out of the lab and into the field. In such situations, completing complex, sophisticated tasks in a dynamic, partially observable and unpredictable environment is necessary. The use of a Hierarchical State Machine (HSM) for the construction, organization, and selection of behaviors can give a robot the ability to exhibit contextual intelligence. Such ability is important for maintaining situational awareness while pursuing important goals, sub-goals, and sub-sub goals. Using the approach presented in this paper, an assemblage of behaviors is activated with the possibility of competing behaviors being selected. Competing behaviors are then combined using known mechanisms to produce the appropriate emergent behavior. By combining hierarchy with parallelism we present an approach to behavior design that balances complexity and scalability with the practical demands of developing behavioral systems for use in the real-world. The effectiveness of merging our hierarchical arbitration scheme with parallel fusion mechanisms has been verified in two very important landmark challenges, the DARPA Urban Challenge autonomous vehicle race and the International RoboCup robot soccer competition. |

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.
