Obstacle Avoiding Robot 🚘

📌 Overview

This project demonstrates an autonomous obstacle avoiding robot that detects obstacles using an ultrasonic sensor and changes its direction automatically. The robot continuously scans its surroundings and avoids collisions without human intervention.

🎯 Problem Statement

Autonomous robots must be able to navigate safely in unknown environments. Manual control is not practical in dynamic spaces. This project solves the problem by enabling real-time obstacle detection and avoidance.

🛠️ Hardware Components

• Arduino Uno / Nano
• Ultrasonic Sensor (HC-SR04)
• L298N Motor Driver
• DC Motors
• Robot Chassis
• Battery Pack
• Connecting Wires

💻 Software & Tools

• Arduino IDE
• Embedded C/C++

⚙️ Working Principle

1. Ultrasonic sensor measures distance to nearby objects.
2. Arduino calculates distance using echo time.
3. If an obstacle is detected within a threshold distance, the robot stops or changes direction.
4. Motor driver controls motor movement accordingly.

✨ Features

• Real-time obstacle detection
• Automatic direction control
• Collision-free navigation
• Simple and cost-effective design

🧪 Results

• Successfully avoids obstacles in real-time.
• Smooth movement and quick response.
• Reliable distance measurement.
