ABSTRACT:
This research paper presents the design and development of a Wi-Fi controlled robotic car integrated with an ultrasonic distance-monitoring system for collision prevention. The system uses an ESP32 microcontroller as the central processing and communication unit, an HC-SR04 ultrasonic sensor for real-time distance measurement, and an L298N motor driver for bidirectional motor control. The car can be controlled remotely using a smartphone or browser interface via Wi-Fi. When the car moves forward, the ultrasonic sensor continuously monitors obstacles, and the system automatically halts motion when an object is detected within a predefined safety range. The prototype aims to provide a low-cost, educational, and reliable robotics platform suitable for IoT experimentation, laboratory demonstrations, and student mini-projects. The system’s performance, advantages, limitations, and potential enhancements are discussed in detail
