| Abstract | This paper studies the use of Cooperative Dual-Task Space (CDTS) as an efficient approach for the whole-body motion balancing problem for humanoid robots. The CDTS variables have been used efficiently to describe and control coordinated motions of dual-arms. Similarly, the concept of CDTS variables can be extended to describe the constraints and the control of humanoid legs. When the leg motion is described and controlled by CDTS variables, the variables regarding the feet constraints and the control variables in the leg motion regarding the waist movement can be nicely decoupled. One of the CDTS variables can be used to describe the constraints on the feet, and the constraints can be expressed independently of the support-foot changes. The proposed CDTS-based method provides an efficient way to stabilize the merged whole-body motion by modifying the horizontal waist position by a coordinated motion of both legs while satisfying the changing constraints on both feet in the lower-body motion. Thus, the proposed CDTS-based method provides the possibility of generating a large library of whole-body motions for a humanoid robot by combining an upper-body motion captured from humans and lower-body motions generated by an existing biped walking pattern planner. The performance of the proposed CDTS-based approach was validated through extensive simulations including cases that showed a HOAP-2 robot walking on a flat terrain and climbing up the stairs with a rapid upper-body movement. |

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.
