—The key innovation is a web-based interface hosted directly on the ESP32, eliminating the need for dedicated appli cations or internet connectivity. This design choice enhances user friendliness and reduces system complexity. The hardware setup involves fundamental components: an ESP32 development board, an L298N motor driver, and standard DC motors, ensuring cost effectiveness and ease of replication. The ESP32’s dual-core ar chitecture and integrated Wi-Fi module allow it to simultaneously serve web pages and manage real-time motor control. Users can access the intuitive web interface through any Wi-Fi enabled device’s browser to send commands to the car. The commands are wirelessly transmit in the ESP32, which then processes them to drive the L298N motor driver. The L298N, in turn, regulates the power supplied to the DC motors, enabling precise control over the robot’s movement. Primarily intended for educational pur poses and rapid prototyping, this project effectively demonstrates the principles of wireless robotic control with minimal hardware and software overhead. The app-free and internet-independent nature of the system makes it an ideal platform for students, hobbyists, and researchers exploring robotics and the Internet of Things. The paper elaborates on the hardware configuration, the software implementation on the ESP32, and the functionality of the user-friendly web control interface. The advantages of this approach, including its simplicity, low cost, and self-contained operation, are also discussed. Index terms such as ESP32, Wi-Fi robot, IoT car, web server control, and remote control categorize the core aspects of this work. This research contributes to making wireless robotic control more accessible and easier to implement
