The XO laptop sits on a baseplate which also has [http://www.robotis.com/xe/dynamixel_en 2 motors], [http://www.fing.edu.uy/inco/proyectos/butia/mediawiki/index.php/Kit_de_sensores sensors] and [http://www.fing.edu.uy/inco/proyectos/butia/mediawiki/index.php/Pack_de_bater%C3%ADas battery pack].

The motors and sensors interface to the XO through a small PCB, either [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 [http://www.fing.edu.uy/inco/proyectos/butia/mediawiki/index.php/Usb4butia Usb4butia PCB] which uses a PIC 18F4550 microprocessor. The connection between the XO and the small PCB is by USB cable. The cable must stay connected while the program is running.

The robot's controlling program runs on the XO laptop, typically TurtleBots, the pallette of blocks is shown below. Control by programs in [http://www.fing.edu.uy/inco/proyectos/butia/mediawiki/index.php/Butialo Lua] or [http://www.fing.edu.uy/inco/proyectos/butia/mediawiki/index.php/Python Python] are also possible.
