Abstract: The rapid advancement of robotics and Internet of Things (IoT) technologies has enabled the development of intelligent systems that can perform tasks both autonomously and remotely. Robotics is widely used in industries, smart homes, and security systems. One of the major challenges in robotics is ensuring safe navigation in environments where obstacles are present.This project focuses on designing a WiFi-controlled obstacle-avoiding robot using the ESP8266 microcontroller. The system combines wireless communication, embedded programming, and sensor-based obstacle detection. The ESP8266 allows the robot to be controlled remotely through a web interface, where users can send commands like forward, backward, left, right, and stop using devices such as smartphones or laptops. In addition to manual control, the robot operates in an automatic mode where it detects obstacles using an ultrasonic sensor. When an obstacle is detected, the robot stops and uses a servo motor to scan its surroundings and choose the safest path. A 16×2 LCD with I2C interface displays real-time data like distance and movement status, making the system efficient, cost-effective, and suitable for educational and basic automation applications.
