Development of a Voice-Operated Robotic Hand for Stroke Patients

Stroke is a leading cause of long-term disability worldwide, often resulting in impaired motor function, particularly in the upper extremities. To aid stroke patients in their recovery process, this study presents the development of a Voice Operated Robotic Hand (VORH) using the Atmega328 microcontroller. The VORH is designed to assist stroke patients in regaining hand dexterity and mobility by providing a user-friendly and accessible interface through voice commands. The system employs an Atmega328 microcontroller to control the robotic hand's movements and receive voice commands from the user. A speech recognition module is integrated with the Atmega328, allowing real- time voice interaction with the robotic hand. The user's voice commands are processed and interpreted, enabling precise control of the hand's grip and movement. The robotic hand is equipped with sensors and actuators to mimic the natural movement of the human hand. These sensors enable the hand to adapt to various objects' shapes and sizes, providing a more versatile and practical rehabilitation tool. The VORH's user interface is designed to be intuitive, enabling stroke patients to operate it with ease and minimal physical effort. Preliminary testing of the VORH has shown promising results in terms of usability, accuracy, and safety. Stroke patients have demonstrated the ability to control the robotic hand effectively, thereby enhancing their rehabilitation experience. The Atmega328 microcontroller's efficiency in processing voice commands and controlling the robotic hand's movements has proven to be a valuable asset in this project. The development of a Voice-Operated Robotic Hand using the Atmega328 offers an innovative solution to address the rehabilitation needs of stroke patients.
