| Abstract | We present a geometric approach to the dynamic analysis of manipulation systems of a rather general class, including some important types of manipulators as, e.g., cooperating, super-articulated, and whole-arm manipulators. The focus is in particular on simple industry-oriented devices, for which a minimalistic design approach requires a clear understanding of mobility and graspability properties in the presence of kinematic defectivity. The paper discusses the dynamics of these systems, and considers how their structural properties (in the classical system-theoretic sense, i.e., stability, controllability, observability, etc.) are related to frequently used concepts in robotics such as "redundancy", "graspability", "mobility", and "indeterminacy". Less common or novel concepts, such as those of "defectivity," "hyperstaticity," and "dynamic graspability", are elicited and/or enlightened by this study. Some important practical consequences of the limited control possibilities of defective systems are thus put into evidence. Finally, a standard form of the dynamics of general manipulation systems is provided as a compact and readable synopsis of the dynamic structure. The form is a valuable tool for synthesizing dynamic controllers for such systems, especially suited to geometric control design methods. |

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.
