| Abstract | It is certainly important to get 3D geometric shape models of unknown objects. We try throughout this paper to make humanoid robots construct such models themselves. To reach this objective, we propose a method consisting in observing objects from multiple view points with re-grasping in order to get non-occluded model. In this paper, we especially focus on the selection algorithm of the next grasp position from computed candidates. This problem is expressed through a graph search problem. The nodes represent grasp positions, and they are connected when robots can re-grasp from one grasp position to the other. Of cource when the shape of an object is unknown, it is difficult to solve this problem. This is why we propose a heuristic method to select next grasp position only using grasp position information, so to be able to adapt to objects which 3D shape information is updated online. We compare the result with this method with the optimal solution available when 3D shape information is given. Finally we show the validity of this heuristic method in real time observation by comparison between these two solutions from the standpoint of the acquired 3D shape percentage and the number of regrasping. |

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.
