| Abstract | A new control algorithm for an object manipulation task by a wheeled mobile robotic system with flexible members is studied here. Flexible members such as solar panels of wheeled mobile robotic systems and their flexible joints during a maneuver may get stimulated and vibrate. Therefore, such vibrations will cause some oscillatory disturbance forces on the moving base and manipulated object, which in turn produces error in the position and speed of the manipulating end-effectors. To encounter these flexibility effects, it is assumed that these members are activated. In this paper, first the system dynamics is partitioned into two rigid and flexible bodies' motion. Next, an applied model for control implementations on compounded rigid-flexible multi-body systems is developed. Then, based on a designed path/trajectory for a wheeled mobile robotic system, the Adaptive Hybrid Suppression Control (AHSC) is applied to perform an object manipulation task by such complicated rigid-flexible multi-body systems. Finally, a wheeled mobile robotic system is simulated which contains two 2-DOF planar manipulators with flexible joints, appended with two solar panels. Obtained results reveal the merits of the proposed model and new control algorithm which will be discussed. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
