Project philosofy & description
This project concerns the ways to convert virtual information into the real world objects and try to simplify access to digital fabrication tools.
Tweet A Ball (TaB) is a robot designed to "draw" the text of tweets containing specific hashtags on balls, eggs and other spherical surfaces. Unlike other Eggbot and similar, TaB is fully autonomous and doesn't require an external control station (PC) nor software for processing text draw
TaB was designed by Fablab Napoli within IntelMaker competition for the occasion of Maker Faire 2016 exhibition. The project, mainly intended for teaching purposes, aims to explore Intel Edison platform capability.

How does TaB works?
Exploiting the power of Intel Edison, TaB can connect directly to internet and scan the Twitter stream to research specific topics of discussion (hashtags). Identified a message matching the search criteria, the software inside the robot converts the text in lines, curves and points. Finally the whole is converted into a sequence of movement commands that trigger the writing arm.
The entire software stack is designed specifically for the Intel Edison platform and consists of the following modules:
The modules Dispatcher, Host and Post-processors have been designed in Python and are executed by Intel Edison CPU, while the firmware module has been adapted for Intel Edison MCU.
For this project we've used an Intel Edison development board as basis for the prototype, plus other hardware equipment showed later in this instructions.
