�olytechnic as a �oca�onal educa�on ins�tu�on has to �eep upda�ng its curriculum with inno�a�on and the latest technology applica�on in industry and domes�c. Teaching learning process in the classroom also has to be based on technology applica�on. The teachinglearning process will be more e�ec��e and interes�ng by in�ol�ing the students to be more pro-ac��e and crea��e. To engage the students more, the teacher needs a teaching-learning media, and one of these media is simula�on so�ware. The �isualiza�on of the simula�on a�racts students� interest and enhances students� crea��ity. This paper proposes the applica�on of an open source and low-cost so�ware simula�on as a teaching-learning media to create an interac��e and e�ci�ng robo�cs class. This study will show the design and applica�on of fuzzy logic controller in a mobile firefighter robot, and simulate the design in SCILAB, an open source so�ware, and in �obotSim, a low-cost so�ware. This alterna��e of open source so�ware can be as good as the high-end ones. This paper shows that the applica�on of fuzzy logic controller can be fun and �ariant for students to en�oy the class. The contribu�on of this research is to show and encourage teachers and students to learn robo�cs and ar�ficial intelligence in an interac��e classroom using free so�ware and also encourage them to search more alterna��e open source so�ware.
