Abstract - Automation has become an essential requirement in modern industrial environments to achieve higher productivity, accuracy, and operational efficiency. Among various automation solutions, pick- and-place robotic systems play a crucial role in material handling, sorting, packaging, and assembly operations. Traditional pick-and-place systems are generally rigid, preprogrammed, and lack adaptability, as they depend on fixed coordinates or mechanical sensors. These limitations reduce flexibility and increase manual intervention when object position, orientation, or type changes. To overcome these challenges, this project focuses on the design and development of an Industrial Pick and Place Robot using Image Processing, which integrates computer vision, machine learning, and robotic control to enable intelligent and autonomous operation. The proposed system employs a camera-based vision module to continuously monitor the workspace and capture real-time images. These images are processed using OpenCV and deep learning techniques such as Convolutional Neural Networks (CNN) integrated with the YOLO (You Only Look Once) algorithm. The image- processing unit is capable of identifying and classifying objects based on their visual features, particularly geometric shapes such as circles and triangles. Once an object matching predefined selection criteria is detected, its position coordinates are extracted and transmitted to the control unit through serial communication.
An Arduino Uno microcontroller acts as the central controller of the system. It receives object location data from the image-processing module and generates appropriate control signals to drive the robotic arm. The robotic arm is designed with four degrees of freedom and is fabricated using 3D-printed components. MG995 servo motors are used to achieve precise and smooth joint movements, while an electromagnet is employed as the end-effector to securely pick and release metallic objects. The coordinated operation between the vision system and the robotic arm enables accurate pick-and-place actions from one location to another without human intervention.
