Design and Fabrication of Robotics Arm with Smartphone Control

The development of a robotic arm with smartphone control represents a significant step toward affordable automation for educational, industrial, and domestic applications. This research focuses on the design and fabrication of a low-cost robotic arm capable of performing pick-and-place operations through wireless communication. The system integrates an Arduino microcontroller, servo motors, and a Bluetooth module, enabling real-time control via a smartphone application. The robotic arm is designed to mimic human arm movement with multiple degrees of freedom, offering precision and flexibility. The fabrication involves lightweight materials to ensure portability and energy efficiency, powered by a 9V DC battery. Experimental testing demonstrates that the arm can successfully lift, move, and position small objects with stability and accuracy. The results confirm that smartphone-based control provides a user-friendly and efficient interface for robotic operations. This project serves as a foundation for further advancements in automation, especially in small-scale industries, laboratories, and educational robotics systems.
