A simple, cheap and easy to use line following robot for educational use.
Line following robots are always a good alternative for learning about the motion, sensing and programming of small mobile robots. After competing several years on robotics competitions like Robocup Junior Rescue Line, I decided to build a small and simple robot for everybody to learn and play with this kind of bot. The opportunity came when I partnered up with two friends and their companies to build small line-follower robots for a workshop at the 2016 Arduino Day Event that we hosted.
- Engenhoteca, helped me with lasercutting the wood material.
- Robocore, gave all the hardware needed for 20 robots.
Check our Instructables for the detailed step-by-step instructions of how to assemble one of this robots.
-
The files on the DXF's folder are all the parts that you need to have lasercutted on 3mm wood (Plywood or MDF) to start the building.
-
There's also a passive "wheel" that is 3D Printed, at the STL's folder.

The programming is pretty straightforward. You must have installed Arduino IDE on your computer, or the program you like to use to upload to an arduino(and arduino-like boards).
This work is in progress, and all definitely finish this part later!
Thanks to my friends:
- Marcos de Oliveira, that helped me lasercut and 3d print parts for the 20 first bots.
- Ivan Seidel, helped me build the 20 first bots and got me into the Arduino Day 2016 where the workshop was held.
- Rafael Riciardi, gave me a hand on assembling the first 20 robots.
- Vinicius Milani, also gave me a hand on assembling the first 20 robots.
