Physical disability is a curse to human life. Idea of our project "The Intelligent Wheelchair for Handicapped Persons" has occurred to help the handicapped persons. The fundamental operation of the wheelchair is to facilitate handicapped person with safe movement. For ensuring the safety of movement, obstacle sensing, crack detection and living being identification features have been included. Additionally, a voice controlled LCD has been provided considering the case of auditory disabled people. Access to control basic home appliances has also been offered.
