Abstract

The development of robotic arm control systems for industrial automation is essential to enhance productivity and accuracy in various tasks, especially pick and place operations. This product focuses on designing a 5-degree-of-freedom robotic arm using Arduino technology to achieve this goal. The robotic arm is equipped with MG996R servo motors for the lower three axes which are waist, shoulder and elbow and SG90 micro servos for the wrist roll, wrist pitch and gripper. The system is controlled by an Arduino Mega microcontroller, with wireless communication handled through an HC-05 Bluetooth module. The system is programmed in Embedded C and controlled through a mobile application, which connects to the Arduino Mega with HC-05 Bluetooth module. The system aims to achieve a target accuracy of 95%, a considerable increase from the 90% accuracy observed in earlier implementations. The main idea is to develop a cost-effective and easy to regulate robotic arm that can execute specific movement and handle objects efficiently. The problem statement of this project focuses that numerous companies require a flexible and cheap robotic arm which could be integrated and prototyped quickly. The expected outcome should see the design to enable the robotic arm to work with better precision in pick and place operations, enhancing the industrial automation process. Similarly, testing and validation are expected to identify changes with a improvement in accuracy compared to previous projects.
