Abstract | This paper presents the design of an automatic and intelligent robot arm for object grasping for people on wheelchair with mild to severe disabilities. The system is equipped with stereovision detection in order to distinguish different objects from the background. The robot arm has been designed with 6 degrees of action to grasp the detected object from the floor and bring it in front of the user. Two precalibrated digital cameras, facing downward, simultaneously take pictures of the surface where the object is located. Then by applying a new and robust 3D object detection method, the height, location and orientation of the object with respect to the robot's base point are found. The resulting rotation periods are transferred through a designated electronic driver board to the joints' motors via the PC parallel port. Overall, the system detects the object, moves the robot arm to the location of the object, grasps it, moves it to a predefined position in front of the user, releases the object and finally returns to its home position. The system is automatic and is operated by only one command |

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.
