Artificial intelligence based smart wheelchair

تاریخ : اکتوبر ۲۰۱۵ - جنوری ۱۹۷۰

A smart wheelchair is any motorized chair designed to assist a user with a physical disability, where an artificial control system augments or replaces user control. Its purpose is to reduce or eliminate the user's task of driving a motorized wheelchair. Usually, a smart wheelchair is controlled by a computer using different sensors and techniques in mobile robotics, but this is not necessary. The interface may consist of a conventional wheelchair joystick which can be used to steer around, but this is different from conventional wheelchair, it does not need any manual work since the wheelchair can use control and sensing systems which does not require any physical force. Smart wheelchairs are designed for a variety of user types. Some platforms are designed for users with cognitive impairments, such as dementia, where these typically apply collision-avoidance techniques to ensure that users do not accidentally select a drive command that results in a collision. Other platforms focus on users living with severe motor disabilities, such as cerebral palsy, or with quadriplegia, and the role of the smart wheelchair is to interpret small muscular activations as high-level commands and execute them. Such platforms typically employ techniques from artificial intelligence, such as path-planning. This project is intended to take this a step further by introducing voice recognition so that vocal commands can be processed and then used for movement. Another improvement is to add a smart phone application which uses the gyroscope and accelerometer feature to drive the wheelchair. The wheelchair can be turned on and off using the mobile application to allow use from a distance
