| Abstract | In proposing the jumping mechanism imitating the leg of vertebrate, unique mechanical function of bi-articular muscle was analyzed. The bi-articular muscle is an actuator which exists only in vertebrate. The ground reaction force and/or jumping motion were examined using the following three jumping mechanisms, 1) the mechanism which arranged two actuators on the knee and ankle joint independently (Mechanism-A), 2) the mechanism which arranged two actuators on the knee and ankle joint, and connected two joints by a wire (Mechanism-B), 3) the mechanism which arranged one actuator only on the knee joint, and connected two joints by a wire (Mechanism-C). It became clear that the Mechanism-C is excellent as the result of analyses in this study. A pantograph mechanism is constituted by the wire equivalent to the bi-articular muscle which transmits the joint torque between two joints. And, ideal ground reaction force for jumping motion is generated. Furthermore, the jumping mechanism or robot which has the function of bi-articular muscle was made and the vertebrate like jumping motion was realized. In this study, it is said that the muscular arrangement of vertebrate is ideal arrangement. It is also an answer to the general question why is the crus very thinner than the femur of vertebrate which makes a jump elated. |

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.
