Abstract | Research so far on adaptive bilateral control of master-slave teleoperation systems considers dynamic uncertainties but stops short of considering kinematic uncertainties. However, when picking up objects of unknown lengths, orientations and gripping points, the overall kinematics of a robot in the teleoperation system becomes uncertain. Therefore, new controllers are required that can guarantee the stability and motion tracking performance of the system in the presence of both dynamic and kinematic uncertainties in the master and the slave robots. In this paper, first the uncertain dynamics of the human operator and the environment are incorporated into the dynamics of the master and the slave, respectively. Then, for a teleoperation system with uncertain dynamics and kinematics, nonlinear adaptive controllers are designed for both the master and the slave. The controllers do not need exact knowledge of the dynamics of the master, the slave, the operator, or the environment, or of the kinematics of the master or the slave. The stability and position tracking convergence of the entire teleoperation system are studied. The validity of the theoretical results is verified by simulations. |

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.
