π· ESP32-CAM Remote Controlled Robot Car
π Project Overview
This project uses an ESP32-CAM module to build a Wi-Fi controlled robot car with live video streaming and real-time motor control. The robot can be operated from a mobile browser over Wi-Fi while transmitting live camera feed.
The system runs independently using the ESP32βs built-in Wi-Fi β no external microcontroller required. It is suitable for surveillance, robotics learning, and IoT-based automation projects.
βοΈ How It Works (Short & Simple)
Camera streams live video
The ESP32-CAM captures and streams video over Wi-Fi through a web server hosted on the board.
Mobile connects via Wi-Fi
User connects to the ESP32βs IP address using a smartphone browser.
Motor driver controls movement
A motor driver module (like L298N or L293D) receives GPIO signals from ESP32 to control direction:
- Forward
- Backward
- Left
- Right
- Stop
Real-time monitoring
User sees live camera feed while controlling the robot.
Standalone system
No cloud dependency β works on local Wi-Fi network.
