Development of a Robotic Arm with Vision-Based Pick and Place Functionality

In this paper, we present the design and implementation of a robotic arm system equipped with both manual and automated control capabilities, facilitated by an Arduino Uno microcontroller and various peripheral modules. The robotic arm is constructed using three SG90 and three MG996R servo motors, providing multi-degree-of-freedom movement for precise manipulation tasks. Integration of an HC-05 Bluetooth module enables wireless communication, allowing remote control and programming flexibility. A key feature of our system is its vision-based pick and place functionality, enabled by the inclusion of an OV7670 camera module. Utilizing image processing algorithms, the camera captures real-time footage of the arm’s surroundings, facilitating object recognition and localization. This enables autonomous operation, where the arm can identify and manipulate objects based on predefined criteria. The versatility of our robotic arm system makes it suitable for a wide range of applications, including industrial automation, educational purposes, and research endeavours. By combining mechanical design, electronics, and software development, we demonstrate a comprehensive approach to the creation of intelligent robotic systems.
