8051 soursce code voice controlled wheel chair

Abstract

Powered wheelchairs with the standard joystick interface are unable to control by many people. A voice controlled wheelchair can provide easy access for physical disabled person who cannot control their movements especially the hands. The powered wheelchair depends on the motor control and drive system which consists of ARM Processor LPC2138 and DC Motor. Once the voice recognition system recognizes the voice commands in comparison to the prestored memory, the respective coded digital signals would be sent to ARM Processor which then controls the wheelchair accordingly.

INTRODUCTION

The goal of this smart wheelchair project is to enhance an ordinary powered wheelchair using sensors to perceive the wheelchair's surroundings, a speech interface to interpret commands. Intelligent wheelchair will play an important role in the future welfare society. The use of intelligent wheelchair encourages the view of the machine as a partner rather than as a tool. The population of people with disabilities has risen markedly during the past century. As the data come from the National Health Interview Survey (NHIS), two distinct trends have contributed to the increasing overall prevalence of disability: a gradual rise, due largely to demographic shifts associated with an aging population, as well as a rapid increase that is due to health impairments and accidents. Many individuals have problems to use a conventional wheelchair. A recent clinical survey indicated that 9%-10% of patients who received power wheelchair training found it extremely difficult or impossible to use it for their activities of daily living, and 40% of patients found the steering and maneuvering tasks difficult or impossible. These people, suffering from motor deficits, disorientation, amnesia, or cognitive deficits, are dependent upon others to push them, so often feel powerless and out of control. Intelligent wheelchair has the potential to provide these people with effective ways to alleviate the impact of their limitations, by compensating for their specific impairments. In particular, robotic wheelchairs may help in maneuvering a wheelchair and planning motion. Recently, research of assistant robots is also emerging field of robotic applications.
