| Abstract | Kinematic calibration is one of the most important methods to improve the positioning accuracy of industrial robots. This paper presents an efficient method to calibrate robots kinematic parameters. The proposed method is based on a laser pointer attached on the end-effector and a position sensitive device(PSD) located in the work space of the robot arbitrarily. In the process of robots kinematic calibration, the PSD rotates around a fixed point which keeps the surface of the PSD on the same sphere surface. In each position of the PSD, the laser beam is brought to the center of the PSD surface with various positions and orientation and the corresponding joint angles are recorded. Consequently, an optimization model was formulated and the Levenberg-Marquardt(LM) algorithm which used to solve the non-linear minimization problem was employed to identify the errors of the kinematic parameters. Simulations and experiments were performed and verified the feasibility of the proposed method. |

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.
