| Abstract | Dynamic simulation of manipulators interacting directly with human is crucial for predicating their performance before the actual use. This paper describes the dynamic analysis and simulation of a novel multi-function mobility assistive device for elderly. The device is designed to help patients who suffer from degradation of the lower limbs muscular strength. Rather than one function device, the proposed device is intended to assist in different lower limb activities, namely, sit to stand and walking activities as well as transfer paralyzed patients from bed to wheelchair and help them stand in upright position to improve blood circulation. The device is based on a non-conventional structure of a 3-RPR planer parallel manipulator which has high rigidity due to the parallel structure. It has some interesting kinematic advantages that facilitate structure and control design. Dynamic model for the assistive manipulator is derived using the first type of Lagrange's equations. A PD-computed torque controller is tuned using genetic algorithm. Simulation results prove high performance of the proposed device in terms of the low tracking error and the proper actuator force. |

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.
