Abstract | The development of a wall climbing robot which is able to move over the surface of "3-dimensional terrain", a terrain including floor, wall, ceiling of any kinds of structures with agility and terrain adaptability is strongly demanded in many industries. The conventional wall-climbing machines were far from fulfilling the demand, the authors thus have been developing a wall-climbing robot with four-terrain-adaptive legs and basic mobilities were already demonstrated by the manufactured prototype model NINJA-I. However, as there are almost no examples of wall-climbing quadrupedal animals and conventional machines, the gait control method specific for the quadruped wall-climbing is not at all known by now. As the first step to consider a general gait problem of a quadruped wall-climbing robot, this paper investigates a gait of the robot on a vertical and flat wall. The gait is analyzed with the criterion to maximize the locomotion speed under the constraints of predetermined conditions of the supporting-legs position, order and phases of swing legs to prevent turn over motion. As a result of the analysis, the optimal standard gait, named "Wall Gait", is shown to maintain foot posture of /spl Lambda/ shape and moves the leg in the order of leg1-leg2-leg4-leg3 in static walk and the order of "pace" in dynamic walk. |

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.
