What if your robot could see the world around it? In this exciting DIY project, we dive into the fascinating world of robotics by building an obstacle-scanning robot with a 180° radar system using Arduino. This hands-on challenge transforms simple electronic components into a smart machine that can detect obstacles, scan its surroundings, and respond in real time-just like autonomous robots in the real world. As you build, you'll explore how ultrasonic sensors, servo motors, and Arduino programming work together to create a sweeping radar motion. Every rotation teaches you something new-about distance measurement, logic building, and problem-solving through code. This project isn't just about assembling parts. It's about: Understanding how robots sense their environment Learning the basics of automation and AI-inspired thinking Turning curiosity into confidence through experimentation Perfect for students, beginners, and young makers, this obstacle-scanning robot proves that learning engineering can be fun, creative, and incredibly empowering.
