| Abstract | The space environment is very demanding and every mission requires careful assessment and preparation. This is especially true when operations are rather challenging as in the case of a multibody spacecraft and grasping mission. Therefore, the design and set-up of specific ground simulation techniques is mandatory in order to define and study the control law strategies to be later applied in orbit. The paper depicts the experimental activities carried out at the University of Rome “La Sapienza” to experimentally simulate planar, controlled operations of orbiting manipulators. The architecture of the set-up, including the choice for limiting the friction, is discussed. Hardware selection and assembly issues, with reference to performance expected by simulation set-up, are detailed. Special attention is devoted to the kinematic state determination and trajectory reconstruction, to be obtained by sensors and devices located onboard the manipulators and validated by external means like webcams, which become a part of the simulation testbed itself. Relevant performance of each subsystem is described, and verified in robust closed loop grasping maneuvers. A second application of the same set-up, which is also helpful and currently used in formation flying studies, is introduced. |

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.
