The connection between the XO laptop and the small PCB is by USB cable. The cable must stay connected while the program is running. | The motors and sensors interface to the XO through a small PCB, either an [http://arduino.cc/en/Main/ArduinoBoardMega Arduino Mega] and [http://www.fing.edu.uy/inco/proyectos/butia/mediawiki/index.php/Construccion_shield_v1.0 shield] or a [http://www.fing.edu.uy/inco/proyectos/butia/mediawiki/index.php/Usb4butia Usb4butia PCB] (which uses a PIC microcontroller).
