 Dies ist mein kleines Roboterprojekt. Eine eigene Platine mit einem AtMega2560 steuert den Roboter. Angeschlossen sind unter anderem mein [Bluetooth Modul][1], eine [Gameboy Kamera][2] und mein [RAM Modul][3]. Vom [Roboternetz][4] stammen das [RN-KeyLCD][5] und der [RN-VN2 Motortreiber][6].
 
 Die aktuelle Software sowie Eagle Dateien der Platine finden sich auf [GitHub][7].
