Design and Implementation of an Arduino-Based Robotic Arm with Omnidirectional Mobility for High-Precision Industrial Automation

The development of a robotic arm control system for industrial automation is crucial in enhancing productivity, accuracy, and efficiency in various tasks, particularly in pick-and-place operations. This project focuses on designing a 5-degree-of-freedom (DOF) robotic arm utilizing Arduino technology, with a combination of MG996R servo motors for the primary joints (waist, shoulder, and elbow) and SG90 micro servos for wrist movements and the gripper. The robotic arm is designed to execute precise movements, making it suitable for industrial applications that require automated object handling. A significant enhancement in this system is the integration of mecanum wheels, which provide omnidirectional mobility, allowing the robotic arm to navigate complex environments effortlessly. This feature ensures greater flexibility and adaptability, making the robotic arm suitable for tasks in dynamic and confined workspaces. The system is powered and controlled by an Arduino Mega microcontroller, which acts as the central processing unit for coordinating motor movements. Wireless communication is facilitated through the HC-05 Bluetooth module, enabling seamless control via a custom-designed mobile application. The mobile interface allows users to operate both the robotic arm and its mecanum wheel-based platform, offering an intuitive and user-friendly experience. The main objective of this project is to develop a cost-effective and easily controllable robotic arm that can perform pick-and-place operations with high accuracy. The system aims to achieve an improved target accuracy of 95%, a notable enhancement compared to the 90% accuracy observed in previous implementations. The problem statement emphasizes the growing demand for affordable, flexible, and highly functional robotic arms that can be quickly deployed in various industries, including manufacturing, logistics, and automation sectors. To validate the system’s effectiveness, extensive testing and performance evaluation will be conducted, focusing on precision, mobility, and response time. These tests will confirm the system’s ability to enhance industrial automation by improving movement accuracy and providing seamless mobility through mecanum wheels. Ultimately, this project aims to contribute to the advancement of industrial robotics, offering a versatile and efficient solution for modern automation needs.
