Escornabot Ogaki Assembled + Chasis (w/o microcontroller)

Have you heard of the Escornabot? It's a family of open source hardware educational robots originally created by a group of teachers in Spain. In a nutshell, the Escornabot is a DIY kit where, after soldering all of the components on the board, mounting the board on its plastic chassis, and programming the Arduino board on it, you end up with a ready to go educational product. 

The robot can then be used in -at least- three different educational activities: mounting the robot, programming it with code (using the Arduino IDE), and controlling it from its keyboard using standard firmware.
Escornabots are meant to be used in primary education to teach kids about spacial orientation, basic mathematics, and computational thinking concepts like sequences and the like.
Escornabots are named after species of beetles. Ogaki, besides a Japanese city, is the name of one of those species.
This item includes all of the parts to mount your own Escornabot Ogaki with motors, battery holder and the plastic chassis  (all chassis have green, white and orange pieces). Also, the kit includes a metal ball and two rubber rings to build the chassis for the robot. Note that this design is compatible with Arduino Nano as well.
