| Abstract | This paper studies the problem of moving target tracking in 2D space by omnidirectional mobile robots using stereo vision. For a given moving target, by extracting its feature points using vision, the relative motion, including both position and velocity errors between the target and the robot can be estimated. Unlike the case of nonholonomic robot tracking whose path planning is a difficult task, in our vision based tracking of omnidirectional robots, the tracking path is directly specified by the estimated tracking errors. Given the dynamics of robots, a PD control is proposed which ensures the asymptotic stability of the tracking error if the target is moving with constant linear and rotational velocities, or the bounded-input-bounded-output (BIBO) stability if the target is moving with varying but bounded rotational and linear accelerations. Simulation results show the efficiency of the algorithm. |

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.
