DESIGN AND DEVELOPMENT OF IOT-BASED 6 DOF ROBOTIC ARM WITH MOBILE PLATFORM

Abstract

This project presents the design and development of an IoT-based 6 Degrees of Freedom (DOF) robotic arm integrated with a mobile platform, controlled remotely via a smartphone using the Blynk application. The system combines robotic manipulation and mobility, enabling it to perform complex tasks such as object handling and movement across different locations. The robotic arm is powered by six MG995 servo motors, allowing precise control of each joint, while the mobile base is driven by BO motors and controlled through an L298N motor driver. The entire system is managed by a Node MCU (ESP8266) microcontroller, which connects to the internet and communicates with the Blynk app for real-time command execution. A 12V Li-Po battery serves as the main power source, and a buck converter ensures stable voltage regulation for the electronic components. This project demonstrates the integration of Internet of Things (IoT) technology with robotic systems, offering remote accessibility, portability, and flexibility. It is suitable for applications in automation, remote monitoring, object manipulation, and educational robotics. The prototype provides a strong foundation for future enhancements such as autonomous navigation, sensor integration, and AI-based control.
