1. Introduction  Human Following Robot ek aisa robot hota hai jo sensors ki madad se insaan ko detect karke uske peeche-peeche automatically chalta hai. Ye project robotics aur automation ko samajhne ke liye beginners ke liye bahut useful hai. 2. Objective • Human ko detect karna • Direction ke hisaab se robot ko move karna • Automation ka basic concept samajhna 3. Working Principle Robot me IR ya Ultrasonic sensors lage hote hain. Jab sensor insaan ko detect karta hai, microcontroller motors ko command deta hai. Insaan aage badhta hai to robot aage badhta hai, rukne par robot bhi ruk jata hai. 4. Components Used 1 Arduino Uno / Nano 2 IR Sensor / Ultrasonic Sensor  3 Motor Driver (L298N / L293D)  4 DC Motors + Wheels  5 Battery  6 Connecting Wires & Chassis 5. Applications 1 Shopping malls & hospitals  2 Home assistant robot  3 College mini projects  4 Learning robotics basics 6. Advantages 1 Automatic operation  2 Beginner-friendly ...
