Voice and Joystick Controlled Wheelchair for Physically Disabled Person

The Wheelchair Voice Controller project is designed to assist individuals with physical disabilities by enabling wheelchair operation through voice commands. The system uses a voice recognition module connected to a microcontroller that interprets commands such as “forward,” “backward,” “left,” “right,” and “stop,” and sends corresponding signals to motor drivers that control the wheelchair’s movement. This hands-free control method provides users with greater independence and ease of navigation in daily environments. To enhance reliability, the system also includes a joystick as an alternative manual control. This dual-mode functionality ensures continuous operation in scenarios where voice control may be ineffective, such as noisy surroundings or when the user is unable to speak. Both input methods allow smooth transitions and responsive control for better user experience. The project emphasizes a balance between performance, cost-effectiveness, and usability, aiming to create a practical and affordable solution for people with mobility challenges. Overall, the project addresses the growing need for intelligent assistive technologies that improve the quality of life and independence for individuals with physical limitations.
