| Abstract | In order to reduce the operator's working strength and the damage that comes from the unknown obstacles to the telerobot, an obstacle avoidance algorithm for the telerobot is proposed based on virtual torque. In this algorithm, the virtual force between robot and obstacles is established using the principle of “the same sex is repulsive and the opposite sex is attractive”. The function model of the virtual torque and the joint velocity is derived from the dynamic equation of the robot. Using this model, the robot can avoid obstacles real-time by adjusting the joint velocity. To verify the effectiveness and practicality of the algorithm, the simulation model of the robot is built using Matlab. At the same time, the continuous path movement of the robot is simulated in three-dimensional space in which there are dynamic obstacles. The simulation results show that the robot can return to the expected path quickly after it avoids the obstacles successfully. |

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.
