AR.L.O. is a 3D printed 2-wheels robot based on Arduino. It features: an OLED display, an ultrasonic sensor, a bluetooth module and 2 modified servomotors. AR.L.O. is very easy to print, assemble and program and is very good for kids and project schools since allows to bring together all makers experiences: 3d printing, embedded electronics, mechanics and programming.

A simple source code is provided on the github account and full assembly instructions on the documentation page.


Here is a video showing AR.L.O.:



Here is another video where I talk about it (sorry, it's only in Italian language...):
