Abstract | This paper addresses the problem of whole-body trajectory generation in humanoid robot performing a manipulation task. The approach utilizes coordination of prioritized movements of the Center of Mass (CM), foot and hand. A Center of Mass trajectory is computed from the desired Zero Moment Point (ZMP) trajectory while stepping. The ability to maneuver horizontal CM is related to the ability to maintain balance. Generally, the vertical CM movement is left unspecified. In this paper, the horizontal CM manipulability is associated with the CM height through the shape of the CM manipulability ellipsoid. A posture with a larger horizontal CM manipulability ellipsoid is more stable in the sense that its CM can be easily maneuvered as required by the desired ZMP with less joint effort. Computer simulation was conducted to verify the performance and consistency of the proposed approach for generating balance stepping motion with a manipulation task. |

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.
