| Abstract | This paper presents a novel intuitive multi-modal force feedback interface for teleoperation of mobile robotic vehicles. Two different force feedback interfaces are considered: a force feedback joystick and a novel force feedback trackball. The joystick considered is based on the admittance user interface developed by the authors in earlier work and is configured to servo velocity of the vehicle. The force feedback trackball is configured to map vehicle velocity directly to trackball velocity, exploiting the effectively infinite workspace of the trackball to overcome the classical challenge of servo controlling a slave with infinite workspace using a master device with finite workspace. A key contribution of the paper is to provide a modeling framework, based on the bond graph formalism, that allows the energy consistent modeling of input from an admittance joystick as reference to an internal velocity regulation loop for the vehicle. Once this is implemented it is straightforward to interconnect multiple input devices, and in particular the trackball device, using standard interconnection rules in bond graphs. Experiments were performed, and the outcomes verify the feasibility and effectiveness of the proposed interface. |

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.
