| Abstract | When mechanisms move, because the position of the center of mass (CoM) is changing and also the angular momentum is changing, there is vibration within the system, this can degrade the accuracy performance when the system is used in space. Dynamic balance can be applied to address the above problem. Normally, dynamic balancing is accomplished through employing counter-masses or counter-rotations approach. The potential issue is that the more weight and inertia are included inside the system, which is not cost-effective. Here the authors suggest that one can accomplish dynamic balancing condition based on employing the naturally dynamically balanced mechanisms rather than resorting to the old counterweights approaches. For instance, one can accomplish the reactionless condition based on the reconfiguration concept. One does not employ counter-mass but via reconfiguring the system by shifting the linkage, which does not make the system get to be heavy and therefore, reduce the energy costs and achieve green manufacturing. On the basis of this concept, firstly dynamically balance a single limb based on the reconfiguration technique (decomposition) and then integrate the balanced limbs to construct the entire parallel manipulator (integration); i.e. the decomposition and integration concept. Finally, with the mechanical reconfiguration, the control laws governing the operation of the mechanism also need to be changed. |

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.
