| Abstract | This paper presents a robust and efficient navigation solution for a quadrotor UAV to perform autonomous flight in a confined but partially known indoor environment. The main sensors used onboard of the UAV are two scanning laser range finders and an inertial measurement unit. When the indoor environment is structured and the coordinates of its key corner features are known, the UAV planer position can be efficiently calculated via the measurements from the first horizontally scanning laser range finder. The height of the UAV with respect to the ground can be robustly estimated by the second laser scanner which is mounted orthogonally to the first. Besides, this work also adopts a robust and perfect tracking control method with integral action to enable the UAV to track any smooth 3-D trajectories responsively and precisely. All computation is done onboard by an ARM-based embedded computer with limited processing power. The whole system was successfully tested in the 2013 Singapore Amazing Flying Machine Competition and helped the Unmanned Aircraft Systems Group from the National University of Singapore win the overall championship in the fully autonomous category. |

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.
