Abstract

This project presents the design and development of a voice-controlled robotic arm utilizing a 3D-printed 6 Degrees of Freedom (6DOF) structure. The system integrates Arduino Nano as the microcontroller, MG995 and SG90 servo motors for precise actuation, and the AI Thinker VC-02 offline voice recognition module for efficient voice command processing. The robotic arm can recognize and execute pre-defined voice commands, enabling hands- free operation without relying on external internet connectivity. The offline voice recognition capability ensures robust performance in environments with limited or no network access, making the system versatile and reliable. This project demonstrates the potential for voice-controlled robotics in various applications, such as automation, healthcare, manufacturing, and assistive technologies. By combining affordability, modularity, and practicality, this project provides a foundation for further exploration of human-robot interaction, paving the way for accessible and intuitive control mechanisms in robotics.
