| Abstract | An efficient serial algorithm for the dynamic simulation of a single closed chain is developed. The algorithm is valid for a manipulator with any number of degrees of freedom, N, and it is still applicable when the manipulator is in a singular position. A moving base may also be incorporated into the system. Arbitrary joints are allowed, including multiple-degree-of-freedom joints, and a general contact model is used. The operational space inertia matrix of the chain is used to solve for the unknown contact force vector at the tip, which is then used in the solution for the closed chain joint accelerations. The final solution requires only an additional n/sub c/*n/sub c/ matrix inverse for the closed chain part, where n/sub c/ is the number of degrees of constraint at the manipulator tip. The computational complexity of the algorithm is (ON/sup 3/). The reduction of the order of computation complexity of O(N) is briefly discussed. |

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.
