NXT портретист. Обратите внимание - только обычные детали Лего и уйма программирования.

This robot draws portraits, elaborating photos and images. The software on the PC is developed under MATLAB®, following the ideas of Claude Baumann and his students at (Erik’s XY plotter). The hardware is LEGO MINDSTORMS NXT® and a soft tip pen. Made by Daniele Benedettelli in 2008. More details at
