| Abstract | To be effective in real operations where the environment is continuously changing, robots have to perceive the environment and to adapt accordingly. Unfortunately, there are uncertainties due to ageing of mechanisms, isturbances, backlash, etc. that limit the usage of current control algorithms. In this paper we propose an on-line incremental learning technique using Fuzzy ARTMAP and a pattern selection criterion. The technique starts by training the ANN with a primitive knowledge base. In the presence of new patterns, the criterion-based on the success of the current action-decides autonomously if the pattern should be learned, if the ANN has to recall, or if a recovery action must be performed. The incremental learning approach is based on the online update of the neural network weights and the defined criterion decides should the new pattern be learned. The peg in hole operation (PIH) is selected as the study case in order to evaluate the performance of the technique, which is described in detail as well as the basics of the peg in hole operation. Promising results obtained with real operations with an industrial robot without over training/forgetting is presented that validate the approach. |

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.
