| Abstract | This paper deals with the development and control of an upper limb exoskeleton used for the robotic rehabilitation of stroke patients. Bowden-cable actuators with a high power-weight ratio are applied in the robot system to provide remote power transmission and simplify the mechanical design. The kinematics model of the exoskeleton is analyzed and optimized to eliminate singularities from the desired workplace and achieve natural human-robot interaction. A real-time control system is established in xPC target environment and used to process the feedback signals from the force sensor and potentiometers and execute the control algorithm. An impedance control scheme is developed to provide interactive therapy training to the patients with different disability levels. Preliminary experiments have been carried out in two different training modes to evaluate the performance of the proposed exoskeleton and control approach. |

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.
