| Abstract | This research is concerned with a rubble withdrawal method using force sensors attached on fingertips in order to not break down rubbles during operating for advanced autonomous rescue robots. In rescue fields, mass, shapes, materials and so on of rubbles are unknown. Thus, it is necessary to recognize or estimate a good grasping position without breaking rubbles case by case at the time. Therefore, it is important to detect points on the rubble for that stacked rubble are not broken down by robot !C hand during working. We research an algorithm to estimate characteristics of dynamics of the grasping rubble and grasping position by time response of changes of forces which sensed by force sensors attached on robot ! sG fingers and tracking results of changes of posture obtained by camera images. In this research, we aim to build a rescue robot system for deciding a grasping position without breaking unknown rubbles using force sensors and cameras. In this paper, we show relationships between changes of grasping forces, grasping positions and posture of the rubbles for the basic study. It will be considered that characteristics of dynamics and a grasping position of rubble can be estimated depending on grasping forces. Then, a grasping position is estimated by obtained forces and the validity of the estimation method is shown. |

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.
