Abstract In recent years, there has been a significant increase in research and applications focused on
controlling robotic arms, which are programmable mechanical arms with capabilities similar to human arms.
While the concept of building mechanical arms is not new, the design and specifications can vary widely
across different projects. Our team successfully developed a functional prototype of a voice-controlled robotic
arm specifically designed for individuals with physical disabilities. The primary goal of our project was to
create an affordable robotic hand that is both lightweight and durable. Robotics remains an intriguing and
active area of research within the field of Engineering. Our voice-controlled robot executes predefined actions
based on user commands, which are inputted through an Android phone. Leveraging the widespread use and
user-friendly interface of the Android operating system, we established a Bluetooth connection between the
phone and the robotic arm. The hand's movements are orchestrated using servo motors arranged at specific
angles and positions, controlled by a microcontroller. This setup enables the microcontroller to interpret voice
commands from the smartphone and adjust the grip of the robotic hand accordingly.
