Abstract | We present the approaches to motion planning for a spherical robot with a stable platform, which is not a nilpotent system. Firstly, the kinematic equations of the spherical robot are changed into an affine nonlinear control system without drift. The procedure starts by computing a control that steers the given initial configuration to the desired target configuration for an extended system using a Philip Hall basis of the controllability Lie algebra. The motion planning algorithm for the extended system is proposed. The solution to motion planning for the original system is then obtained using the Philip Hall coordinates. An iterative algorithm is given to generate arbitrary precision, and two methods of motion planning for the spherical robot are summarized. Finally, the simulation results of the motion planning examples illustrate the effectiveness of the methods |

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.
