| Abstract | A compliant wrist combining passive compliance and a displacement sensor has been developed for a robot manipulator to be used in assembly operations. The wrist provides the necessary flexibility to accommodate transitions as the robot makes contact with the workpiece, to correct positioning error, and to avoid high impact forces in automatic assembly. Sensing from the device makes it possible to actively control the contact forces or to compensate the positioning error during motion and contact. The design features of two prototypes of the device are described. A hybrid position force control scheme using the device and incorporating the passive compliance in the design is presented. Two basic primitives in the assembly process, edge tracking and insertion operation with the compliant wrist, are investigated. A fuzzy controller is presented to assign velocity instead of evaluating force zones in insertion. The experimental results show that the system provides a feasible and economical solution to the provision of necessary compliance in automated assembly and manufacturing. |

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.
