dibuRobot

thingiverse

This is a robot based on Makers Box (see link below). It draws, very fun and easy to program (you can test the code blocks with Code.org). It only has 8 printed parts, two 28BYJ motors with drivers, a servo, an Arduino nano, a power button, and a reset button. The program is available on Made in Casa with Arduino (https://www.madeincasa.net/), videos, and all the help you need to make it from scratch. It allows you to add any drawings you want (stars, circles, squares, triangles, any polygon, artwork combining geometric shapes, letters, numbers, words, etc.). With simple programming of the 4 movements (forward, backward, left, right) with parameterized modules and easily buildable functions. Important design note: The marker, pen or pencil should be centered between the two wheels, even if you modify the wheel size and separation. First, I made the Makers Box version, adapting to available materials, but then modified it so that the chassis includes the pen holder and servo support, to ensure alignment. The Arduino programming was done so that there is a part in the main program where you can add the drawing programming without modifying other code. I recommend watching the Makers Box video (Ken Olsen) which I based my dibuRobot on; you'll see that the programming is different, but the idea is the same. It uses Adafruit Pro Trinket 3V instead of Arduino, and there are two other versions with different motors; if you have experience, you can make the adaptations yourself, or I invite you to create your own dibuRobot. I took the idea and here's what's important: the programming and using available elements, in my case Arduino nano. I'm adding the design in FreeCad so you can make your own modifications and creations, which is the fun part of this project. The best thing about this project is that the robot allows you to create a world of figures by modifying the programming.
