| Abstract | In this study, performance test results of “various phases state control” of the semi active knee joint with pneumatic damper have been presented in a comparative manner. Performance tests have been conducted with natural human gait and prosthetic gait via image based motion measurement system and sensor based motion measurement system. Subjects are realized gait onto treadmill with different gait velocities as 1 km/h, 2 km/h and 3 km/h. The phase control of the prosthetic gait is performed under two phase, three phase and five phase scenarios. Under the facts drawn by these performance tests, the optimum control strategy related to phases of gait can be determined in a qualitative fashion and the response of the developed prosthesis under different gait velocities can be measured successfully. Mean absolute knee angle error results from natural gait and prosthetic gait are considered as performance criteria, derived from image based motion measurement system. It is concluded that the response time of the stepper motor causes a major limitation onto proper control over the pneumatic cylinder based prosthesis and associated conclusions are shared. |

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.
