| Abstract | Wheeled mobile robots have been widely investigated and put into many applications such as planet surface exploration fields and other rough terrain situations. Yaw calculation is of importance for mobile robots to autonomously navigate and control. Sensor-based methods for calculating robotpsilas yaw found their limits in the situations where sensor data are not sufficiently applicable or badly noised, especially for planet exploration robots. This paper proposed a novel model-based method for yaw calculation of an all-terrain mobile robot with passively compliant mechanisms. The robotpsilas kinematical model is built considering wheel slips and the physical wheel-terrain contact relationship. Treating the all-terrain mobile robot as a series-parallel multi-body system, we can directly build the robotpsilas kinematical model based on closed velocity chain theory. The yaw calculation can be easily finished by detecting wheel encoder data and solving the kinematical model of the robot. Several experiments were performed to test the validity and usefulness of this method. This kinematics-based yaw calculation method also proved its robustness and real-time performance. |

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.
