Smart Mobility: Voice-Activated Wheelchair for Enhanced Accessibility

This project presents the development of a voice-activated wheelchair designed to enhance accessibility for individuals with limited mobility. Addressing the challenges posed by traditional manual and joystick-controlled wheelchairs, this innovative solution employs readily available and cost-effective components. The system utilizes an Arduino Uno microcontroller as the central processing unit, an L298N motor driver for controlling DC gear motors, and an HC-05 Bluetooth module for wireless communication. A custom-designed interface within a Bluetooth-enabled smartphone application facilitates voice command input, enabling hands-free navigation. This approach offers increased independence and ease of use for individuals who struggle with conventional control mechanisms. The project details the hardware and software implementation, including circuit design, Arduino coding, and app development. Performance testing evaluates the system’s voice recognition accuracy, response time, and maneuverability. The results demonstrate the potential of this voice-controlled wheelchair to significantly improve mobility and quality of life for users with disabilities, offering a more intuitive and accessible means of independent movement. This project highlights the effectiveness of integrating voice control technology with assistive devices to create practical and affordable solutions.
