Line-following robots are a classic first step into robotics. Using just a pair of infrared sensors, a small motor driver, and a microcontroller, you can make a bot that traces a path on the floor.
The project teaches you about sensors, feedback loops, and motor control — core concepts for more complex builds. You can start with a pre-made chassis kit, then experiment with different sensor placements or code tweaks to improve performance.
By Sunday night, you’ll have a robot that can navigate your living room — and the skills to start dreaming bigger.
