Overview

This project implements a remote-controlled robot capable of navigating and performing basic military-style operations using a toy gun. The robot can move in various directions, avoid obstacles, and fire a toy gun safely, all controlled through a simple web interface.

Features

• Wi-Fi Connectivity: Connects to a Wi-Fi network for remote control.
• Obstacle Avoidance: Uses an ultrasonic sensor to detect and avoid obstacles.
• Movement Control: Moves forward, backward, left, right, and can stop.
• Shooting Mechanism: Fires a safe toy gun on command.
• User-Friendly Web Interface: Control the robot from any device with a web browser.

Requirements

Hardware

• NodeMCU (ESP8266) development board
• Motor driver module (e.g., L298N)
• Ultrasonic distance sensor (e.g., HC-SR04)
• DC motors with wheels
• Toy gun (ensure it's safe for use)
• Relay module or transistor for firing the gun

Software

• Arduino IDE with ESP8266 board package installed

Setup Instructions

1. Install Arduino IDE:

   • Download and install the Arduino IDE.

2. Install ESP8266 Board Package:

   • Open the Arduino IDE.
   • Go to File > Preferences.
   • In the "Additional Board Manager URLs" field, add:

     http://arduino.esp8266.com/stable/package_esp8266com_index.json
     

   • Go to Tools > Board > Board Manager, search for "ESP8266", and install the package.

3. Clone or Download the Repository:

   • Clone this repository or download it as a ZIP file and extract it.

4. Open the Code:

   • Open the provided .ino file in the Arduino IDE.

5. Configure Wi-Fi Credentials:

   • In the code, replace your_SSID and your_PASSWORD with your actual Wi-Fi credentials.

6. Upload the Code:

   • Connect your NodeMCU to your computer.
   • Select the appropriate board and port in the Arduino IDE (Tools > Board > NodeMCU 1.0 (ESP-12E Module) and Tools > Port).
   • Click the upload button.

7. Access the Web Interface:

   • Open the Serial Monitor (Tools > Serial Monitor) to find the IP address assigned to your NodeMCU.
   • Enter this IP address in a web browser to access the control interface.

Usage

• The web interface displays controls for moving the robot and firing the toy gun.
• Use the buttons provided to navigate the robot and fire when desired.

Safety Instructions

• Ensure the toy gun used is compliant with local laws and regulations.
• Always supervise the robot during operation, especially when firing.

Future Enhancements

• Autonomous Navigation: Implement algorithms for autonomous movement and targeting.
• Camera Integration: Add a camera for remote surveillance capabilities.
• Advanced Sensors: Integrate additional sensors for improved functionality.
