| Abstract | People with intellectual, motor, sensory damage always faces difficulty in their safe mobility. Thus, for their safe and secure navigation caregivers are needed always. To help these disabled persons for an independent mobility, a new deep learning technique for steering control assist for a powered wheelchair is proposed. In this work, the system learns to direct a powered wheelchair with user satisfaction in new environments. Long-Short Term Memory (LSTM), Bidirectional LSTM (BLSTM ) and Gated Recurrent Unit (GRU) neural networks are used for assisting the guidance of a powered wheelchair. The inputs to these neural networks is dataset of ranges produced by ultrasonic sensors considered to be devoted on the wheelchair and output is the six direction classes. The model predicts the wheelchair direction on the basis of the input data. Later the direction predicted by neural network techniques is been combined with user defining direction which produces the resultant direction so as to avoid objects in the path. The differently-abled person or patients, uses an input method to provide desired speed along with direction and the neural network provides a safe direction for the wheelchair avoiding objects in vicinity. A powered wheelchair model simulation is also done and results are verified with the expected outcomes. The comparison study on numerous parameters concludes that GRU model showed the best performance with overall accuracy of 97.38%. The accuracies obtained from LSTM and BLSTM models are 95.17% and 95.89% respectively. |

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.
