| Abstract | We propose sensor-based path-planning algorithms for a nonholonomic mobile robot. A car-like robot supervised by these algorithms always reaches its target point (position, and orientation) globally while sensing and avoiding uncertain neighbor obstacles locally in a 2-D environment. In general, all the classic sensor-based path-planning algorithms lead a robot to its destination (x,y) quickly in a 2-D unknown search space. Unfortunately, a nonholonomic mobile robot has three degrees-of-freedom (z,y,/spl theta/), and consequently its search space has three dimensions. In this paper, we propose two algorithms NH-I/spl middot/II. NH-I is designed by mixing modified versions of a famous model-based algorithm best-first and the classic sensor-based algorithm Class1. NH-II is designed by mixing modified versions of another famous model-based algorithm depth-first and Class1. BF and DF can investigate around an unknown obstacle whose dimensions are over two. As a result, by the mixture, we obtain three dimensional or more sensor-based path-planning algorithms NH-I/spl middot/II for a nonholonomic mobile robot. Finally, in order to check a real-time property of both algorithms, we compare their search costs with that of a model-based path-planning algorithm A/sub NH/* for a nonholonomic mobile robot. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
