When I joined my school robotics club, I had never held a soldering iron or programmed a sensor. Today, I'm building autonomous robots and planning to major in mechatronics. Here's how it happened.
It started with Lego Mindstorms. I loved assembling the bots, but what fascinated me more was making them do things — follow lines, avoid obstacles, pick up objects. When we moved to Arduino, a whole world of real electronics opened up. Suddenly I was writing C++ code that controlled physical things in the real world.
My favourite build was an object-avoiding rover using an ultrasonic sensor, wheels, and an Arduino Uno. The logic was straightforward: if the distance sensor detects something closer than 15cm, stop the motors, wait, and turn right. Watching it navigate around obstacles on its own felt surreal the first time it worked.
The skills I gained go well beyond robotics: circuit design and wiring, programming in C++, working as a team under competition pressure, and presenting technical projects to judges. Whether or not you go into robotics, these skills apply to everything from AI to mechanical engineering. And honestly — it's just a lot of fun.
