Smart-Obstacle-Avoiding-Robot (2)

This project is an Obstacle Avoiding Robot built باستخدام Arduino.

The robot is designed to move autonomously and detect obstacles using an ultrasonic sensor. When an obstacle is detected, the robot stops, moves backward, and intelligently chooses the best direction (left or right) to avoid the obstacle and continue moving.

Additionally, an LCD screen is used to display the robot’s current status and distance readings.

Tools & Technologies

Arduino Uno

Ultrasonic Sensor (HC-SR04)

Servo Motor

Motor Driver (L298N)

DC Motors

LCD Display (16x2 I2C)

Jumper Wires

Arduino IDE

Libraries Used

Servo.h

NewPing.h

Wire.h

LiquidCrystal_I2C.h

How It Works

The robot moves forward automatically.

The ultrasonic sensor continuously measures the distance ahead.

If the distance is greater than 10 cm → the robot keeps moving.

If an obstacle is detected:

The robot stops

Moves backward

The servo scans left and right

Compares distances

Chooses the clearer path

Continues moving

Usage

Connect all components correctly to the Arduino board.

Upload the code using Arduino IDE.

Power on the robot.

The robot will start moving automatically without user control.

The LCD displays:

“Clear” → path is free

“STOP + distance” → obstacle detected

Features

Fully autonomous movement

Smart obstacle detection and avoidance

Direction decision based on distance comparison

Real-time display using LCD

Simple and efficient design
