| Abstract | The paper presents a new method to realize mobile robot arm grasping in indoor laboratory environments. This method adopts a blind strategy, which does not need the robot arms be mounted any kind sensors and avoid calculating the complex kinematic equations of the arms. The method includes: (a) two robot on-board ultrasonic sensors in base are utilized to measure the distances between the robot base and the front arm grasping tables; (b) an Artificial Neural Networks (ANN) is proposed to learn/establish the nonlinear relationship between the ultrasonic distances and the joint controlling values. After executing the training step using sampling data, the ANN can forecast/generate the next-step joint controlling values fast and accurately by inputting a new pair of real-time ultrasonic measured distances; (c) to let the blind strategy matching with the transportation process, an arm controlling component with user interfaces is developed; and (d) a method named training arm is adopted to prepare the training data for the training procedure of the ANN model. Finally, an experiment proves that the proposed strategy has good performance in both of the accuracy and the real-time computation, which can be applied to the real-time arm operations for the mobile robot transportation in laboratory automation. |

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.
