| Abstract | In this paper, we propose a novel mapping approach to map a human grasp to a robotic grasp based on human grasp motion trajectories rather than grasp poses, since the grasp trajectories of a human grasp provide more information to disambiguate between different grasp types than grasp poses. Human grasp motions usually contain complex and nonlinear patterns in a high-dimensional space. In this paper, we reduced the high-dimensionality of motion trajectories by using locality preserving projections (LPP). Then, a Hausdorff distance was performed to find the k-nearest neighbor trajectories in the reduced low-dimensional subspace, and k-nearest neighbor (kNN) regression was used to map a demonstrated grasp motion by a human hand to a robotic hand. Several experiments were designed and carried out to compare the robotic grasping trajectory generated with and without the trajectory-based mapping approach. The regression errors of the mapping results show that our approach generates more robust grasps than using only grasp poses. In addition, our approach has the ability to successfully map a grasp motion of a new grasp demonstration that has not been trained before to a robotic hand. |

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.
