I’ve wanted to build a robot since I was ten years old watching battlebots after school. Not a fancy one — just something with wheels that can avoid running into walls. Maybe it blinks when you get close to it. That’s the bar.
The thing is, I never started because it always felt like you needed an engineering degree and a workshop full of expensive tools. But then I spent $12 on an Arduino and realized you can make a motor spin with three lines of code. The gap between “I have no idea how robots work” and “I made a thing that moves” is smaller than I thought.
I’m starting here. First project: a small wheeled bot with an ultrasonic sensor that backs up when it’s about to hit something. Parts are ordered. I’ll write it up once I’ve got it moving (or once I’ve burned through my first bag of capacitors, whichever comes first).
Your move: don’t read ten more robot articles. Buy the one Arduino. Make the one motor spin. That’s the whole difference between someone who’s “interested in robotics” and someone who builds robots.
