| Abstract | This paper presents a new device and a method for dynamic manipulation. The device consists of a planar robotic arm and an elastic beam as an end-effector. Using it the elastic end-effector will tend to increase performance and energy efficiency while executing dynamic and repetitive tasks. Through the control of the beam vibration and resonant modes, we modify the state of manipulated objects. For lightweight objects the control is provided through the intermittent contacts without changing dynamics of the beam. However, we show that by using proper synchronization technique continuous-phase contacts are also possible. Juggling and dribbling of a ball are considered to be an alternating non-prehensile catching and throwing task. Such alternating decelerating and accelerating impacts on the ball and the curvature of the beam at the time of impact will stabilize the cyclic orbit of the ball. By proper analysis of continuous-time contact and dynamics of the beam we establish a rhythmic movement of the system. With the variation of frequency and amplitude of the beam it is possible to switch between different dynamic actions such as juggling, dribbling, throwing, catching and balancing. |

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.
