Assistive Device for Locomotion of Visually Impaired and Physically Challenged People

摘要

Dependency for mobility of physically challenged and visually impaired people is a major issue to be focused. To bring a safe and independent movement, a mobility aid with efficient mechanism is a high concern in modern days. The design and development of such device, which is capable of flexible locomotion is being presented on this script. The device is designed using catia software. By two modes of operation the navigation is controlled. In the first mode, the navigation of the unit is governed by the voice command given by the user namely right, left, forward, reverse and stop. The other mode, renders a reliable movement in the known environment which is achieved by feeding in a pre-defined layout. The navigation modes are regulated by a control unit.
