| Abstract | Robot path planning consists of approximating the set of free configurations of the robot by a collection of rectangloid cells at successive levels of approximation and, at each level, searching the graph representing the adjacency relation among these cells. A set of algorithms which specifically address the main two computational issues underlying this approach, cell decomposition and graph searching, has been developed. The authors have implemented a planner which incorporates these algorithms and have experimented with it on examples. The experiments show that the planner is significantly faster than previous planners based on the same general approach. The authors focus on the planner's cell-decomposition algorithms. They use a constraint reformulation technique that consists of approximating the obstacles intersecting the cell to be decomposed by a collection of rectangloids and computing their complements in the cell. Two types of approximations are used, bounding and bounded approximations. This technique produces much less cells than previously proposed techniques, resulting in smaller search graphs. Experimental results are presented. |

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.
