IoT Based 6 DOF Robotic ARM Using Blynk App

IoT Based 6 DOF Robotic Arm Using Blynk App

Project Overview

The IoT Based 6 Degree of Freedom (6 DOF) Robotic Arm Using Blynk App is an advanced automation and robotics project designed to demonstrate precise motion control and remote operation of a robotic arm through the Internet of Things (IoT). The system allows users to control multiple joints of a robotic arm in real time using a smartphone application, making it suitable for industrial automation, research, and educational purposes.

Working Principle

The robotic arm consists of six degrees of freedom, which means it can move in six independent directions—base rotation, shoulder movement, elbow movement, wrist pitch, wrist rotation, and gripper operation. Each joint is controlled by a servo motor.

A Wi-Fi-enabled microcontroller (such as NodeMCU or ESP8266) connects the system to the internet. The Blynk mobile application serves as the user interface, allowing the user to send control commands remotely. These commands are received by the microcontroller and converted into PWM signals to drive the servo motors, enabling smooth and accurate movement of the robotic arm.
