This is an easy-to-mount educational Arduino modular robot designed to print with 3D printers that have small volume size, like Up Mini 2. It is intended to introduce the teenager students to the robotics, programming this robot to accomplish challenges over ground circuits or maps.

The robot control unit is an Arduino Uno card with a specific customized multi-purpose Imagina Shield created by the Robolot Team people from Olot (Girona). The differential drive is based with a couple of chinese geared continuous rotation motors. The frontal part or spoiler have the right place to install two reflective IR sensors to convert the robot into a linefollower robot. And finally, the third wheel is a 16mm marble ballcaster, held by a rear appendix called ballcaster support. This part split is needed in order to fit the chassis core in a small 3D printer.

All the unions are made with M3 metric bolts and nuts.

The power source is a mobile phone powerbank, placed inside the chassis, because is an affordable rechargeable battery.

You can buy the whole electronic's kit, all pieces except the 3d printed chassis and screwdriving, in this link:
