| Abstract | Stereotypic human movements observed in basic experimental tasks have been studied from the viewpoint of optimality with respect to some criteria. Recently, such framework is expected to be applied to understanding skilled realistic movements. This paper deals with a gymnastic maneuver on the high bar, called the kip movement, as a difficult goal-directed task under a nonholonomic constraint. The movements in such system are highly restricted by the constraint; however, it is difficult to imagine that to what extent redundancy remains for achieving the task. Thus, we study on the redundancy underlying the kip movement in this paper. To this end, a simple dynamical model of the kip movement is constructed, where the time histories of angles of actuated joints are parameterized by fifth spline functions. The movement of this model is confirmed to be approximately consistent with a measured movement of an expert gymnast. We propose a systematic method to numerically calculate a set of the spline parameters that achieve the task. A part of the redundancy underlying the kip movement is concretely illustrated. Moreover, we discuss what kind of criteria could be satisfied in the kip movement of expert gymnasts by using the set. |

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.
