| Abstract | Based on the requirements of space robot control system such as high reliability, low power consumption, small size and real-time, this paper presents a dual redundant fault-tolerant strategy for space robot controller. According to the peculiarity of the space robot control systems and its workflow, this strategy is based on the fault-tolerant hardware architecture and the linear running model of space robot software. The two computers communicate with each other by 485 bus and heartbeat line, and share field data through CAN bus in this architecture. The imported criterions include the heartbeat signal, the pattern matching, the dynamic synchronization data and the results returned from the other device. The fault-tolerant strategy which has redundancy criterion is formulated in this paper. This design can not only ensure the time performance of switching between two computers, but also can lower the communication data and improve the reliability and effectiveness of dual-redundant fault-tolerant system. |

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.
