NXT: el robot de Lego

Treball de recerca realitzat per un alumne d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit cientí­fic del Jovent l'any 2009. L'NXT és un robot creat per l'empresa Lego que disposa d'un controlador, de diversos servo motors i de sensors (tacte, llum, ultrasons, so...). Es programa mitjançant un programa especial, pensat per nois i noies de catorze anys, anomenat Lego Mindstorms. S'estudia el funcionament d'aquest programa i les parts del sistema de control del robot. L'estudi engloba el controlador, quatre sensors i els servomotors.
