Dharmesh’s PolyBot project turns the Arduino Uno into a robotic shape racer for a teen learning to code. Gearmotors and a castor wheel drive the bot in a polygon loop, like a square, making a thrilling way to steer coding into motion.
I dreamed of a robot that could zip around in cool shapes like in my video games, so I built my PolyBot project with my Arduino Uno—my first coding try! I wanted my car to roll in a square path, turning sharp corners, powered by motors and a battery, like a robot explorer. It’s so awesome watching it trace a perfect loop!
I used Hubby Gearmotors, a castor wheel, a motor shield, and a battery pack, wiring motor 1 to pins 10 (IN1), 11 (IN2), 5 (EN1), and motor 2 to 12 (IN3), 13 (IN4), 6 (EN2). My C++ code includes #include
I’m hyped to make it wilder next time! Maybe I’ll add a sensor to dodge obstacles, or try a pentagon path. I could even make it beep at corners like a robot racer! I really like coding this with my Arduino, and I can’t wait to show my friends my shape-drawing bot!
Future applications for this project could be epic! I could build a robot mapper that draws floor plans, like SAM’s precise brick-laying. Or a delivery bot that follows square routes in my yard, or a game bot that traces shapes to score points, turning my PolyBot into an autonomous trailblazer!
