“…See the fact is, a lot of research on mobile robot which was successful in facilitating human work in the field of industry. As in investigating suspected hazardous areas to replace the role of humans (Redden, Pettitt, Carstens, & Elliott, 2008), detected objects (Pratama, Dewi, & Oktarina, 2017), measuring pH levels (Dinambar, Sari, & Irdayanti, 2017), transport the tub of trash (Oktarina, Nawawi, & Tulak, 2017). Some research on mobile robot in detecting gas at objects simulate different types of gases, such as octanol ethanol, trinitrotoluene, and tailored to the use of the gas sensor.…”
