| Abstract | Oil spill pollution is a critical issue because of its severe influence on our economy and ecological environment. A large amount of efforts have been made for detection, monitoring and localization of oil spills; however, the cleaning of oil spills remains a challenging problem. Due to dynamic currents on the ocean surface and the limitations of the localization systems, it is not feasible to obtain the exact information of the oil spill location. Therefore, the oil spill region is approximated by an area which may not match the shape of the oil spill. Thus, an effective complete oil spill cleaning algorithm is needed that allows the autonomous vehicle to adapt its trajectories to the oil spill shape. This paper presents a concept of multi-resolution navigation for oil spill clean-up using an autonomous vehicle. The exact a prior knowledge of the oil region is assumed to be unknown or only partially known. This algorithm can dynamically discover and adaptively clean the oil spill in the workspace. A concept of multi-resolution navigation is developed which integrates local navigation and global navigation to avoid being stuck into a local minima that is generally encountered by potential field based methods. The algorithm provides complete coverage and cleaning of the oil spill via minimum overlapping trajectories, and its efficiency is validated on the high-fidelity Player/Stage simulator of mobile robots. |

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.
