Abstract: Nowadays, Technology Advances So Rapidly That Robots Start to Emerge Not Just in Factories, But in Our Daily Lives Helping Us With Big And Small Things. For This Project, We Were Excited to Build Something Helpful and Entertaining: A Human-Following Robot. It Is a Small, Moving Robot Built Out of Low-Budget and Beginner- Friendly Materials Like an Arduino Uno, Ultrasonic Sensors, And A Motor Driver. The Idea Is Simple to Grasp the Robot Follows A Person By Detecting Their Movement And Staying A Safe Distance Behind. This Is How It Works: The Robot Has Ultrasonic Sensors That Send Out Sound Waves. When The Waves Reflect Off Something, The Robot Calculates How Far Away That Something Is. With Two Or More Sensors, It Can Even Calculate The Direction The Person Is Heading. The Arduino Does That Entire Math and Tells the Motors How to Go So The Robot Can Coast Along Smoothly Without Running Into Things. This Robot's Design Is Versatile and Has Numerous Applications In Home Life. It Can Be an Intelligent Shopping Cart That Accompanies You In A Supermarket, A Home Robot That Assists The Elderly, Or A Warehouse Robot That Transports Items From One Point To Another. And as The Design Is Low-Cost and Minimalistic, It Is Perfect For Hobbyists Who Want To Play With Robotics, Sensors, And Embedded Systems. Once The First Version Is Up and Running, There's Plenty Of Scope For Enhancement Such As Incorporating A Camera For Video Tracking, Incorporating Ai To Make It Intelligent, Or Networking It For Net-Based Monitoring. For Hobbyists and Students, It's An Excellent Hands-On Exercise To Learn How Software And Hardware Interface, And A Precursor To Building Sophisticated and Intelligent Robots In The Future.
