Voice Control Wheelchair for Physical Challenged Persons

The main objective of the SMART WHEELCHAIR project is to provide a fully functional system that is helpful for physically disabled people. The system is designed to control a wheelchair using a manual keypad, voice commands, a mobile gyroscope, and a joystick module. The objective of this project is to facilitate the movement of people who are disabled, handicapped, or elderly and are unable to move easily. The goal of this system is to allow such individuals to live a life with less dependence on others for their daily mobility. This can be realized and optimized by using a smartphone device as an intermediary or interface. In this project, interfaces have been designed to develop a program for controlling the movement of the chair and an application that can handle or manage graphical commands. This project uses an Arduino Uno microcontroller circuit and four TT [Traction Motor] DC motors to create the movement of the wheelchair, along with Ultrasonic Sensor sensors to detect obstacles between the wheelchair and its direction of movement. The results and analysis of this innovation are described in this report, and the results show that the module can be used for future research work and to design innovative solutions that meet market needs and public interest.
