| Abstract | Autonomous locomotion in unstructured environments is a great challenge for quadruped robots, especially when there is little knowledge about the environments. Based on stereo vision, this paper proposes a locomotion control system for a quadruped robot that is able to perform adaptive locomotion in unknown environments cluttered with many obstacles. To reduce the negative influence of poor light, surface reflection, and textureless conditions, combined with the sum of absolute difference (SAD) method, an efficient post-processing algorithm is investigated to fulfill disparity estimation. According to the calculated terrain maps, a novel gait planning algorithm, which contains different gaits generation and gait transition, is designed to cross over terrains with enough stability and considerable locomotion speed. Experiments on the real robot of traversing complicated surface with stereo vision demonstrate the effectiveness of our system. Video footage can be seen at: http://irdc.ia.ac.cn/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.
