Industrial Robotic Arm Prototype with Blynk Control

This project demonstrates an industrial robotic arm prototype with 6 degrees of freedom (6 DOF), controlled remotely through the Blynk app using the ESP8266 microcontroller. The robotic arm allows for flexible movement and control over each joint, simulating various industrial automation tasks.

Features

• 6 Degrees of Freedom (6 DOF): Simulates complex movements for realistic task execution.
• Wireless Control with Blynk: Provides easy remote control via the Blynk app.
• Real-Time Control: Adjust servo angles through the Blynk interface, with instant response.
• Simple Setup: Control each servo using sliders in the Blynk app for a straightforward user experience.

Components Used

• ESP8266 Module: For WiFi connectivity and integration with the Blynk app.
• Servo Motors: High-torque servos for each joint (4 controlled in code; expand as needed).
• Power Supply: Sufficient power supply for servo operation.

Code Overview

The code uses Blynk's virtual pins to control each servo:

• V0, V1, V2, V3: Control the angles of servos servo1, servo2, servo3, and servo4.
• V4, V5, V6, V7: Display current servo angles on the Blynk app.

Quick Start

1. Set up WiFi Credentials: Replace ssid and pass in the code with your WiFi network name and password.

2. Configure Blynk:

   • Replace BLYNK_TEMPLATE_ID, BLYNK_DEVICE_NAME, and BLYNK_AUTH_TOKEN with your own from the Blynk project.

3. Wiring:

   • Connect the servos to digital pins D2, D3, D5, and D6 on the ESP8266.

4. Upload Code: Upload the code to your ESP8266 using the Arduino IDE.

5. Control via Blynk: Open the Blynk app and set up sliders on virtual pins V0 to V3 to control the servos.

Code Example

#define BLYNK_TEMPLATE_ID "Your_Template_ID"
#define BLYNK_DEVICE_NAME "ROBOT ARM"
#define BLYNK_AUTH_TOKEN "Your_Auth_Token"

// Include libraries and initialize servos...

Applications

This prototype can be adapted for:

• Pick-and-place operations
• Assembly line tasks
• Remote tasks in hazardous environments

Future Improvements

• Add collision detection sensors for safe operation.
• Incorporate feedback systems for precise position control.
• Expand the system with AI for autonomous functions.
