| Abstract | Construction and evaluation of the two different strategies of force-free control of industrial type robot arm is presented in this paper. First, robot arm dynamic model for two link model and basic structure of force-free control method are described. Then two different force-free control architectures are illustrated. Two different force-free control strategies are force-free control by dynamic external torque and force-free control by dynamic torque independent compensation, respectively. Analysis of the each type of force-free control strategy is carried out for the single link and two links perspectives of industrial robot arm configurations by means of simulations under Matlab/Simulink environment. The model characteristics of the force-free control are exploited to discuss the application scenarios. Moreover, analysis of the force-free control is carried out by using real robot parameters throughout the simulations. Since the force-free control deals with external forces applied on the robot arm, it can be used to illustrate the interactive force control between a human and a robot arm by passive motion over an external force. |

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.
