ROBODEM Remote Monitoring System Using Web/Mobile Applications

This paper presents a remote monitoring system using website and mobile application for detecting explosive gases. The ROBODEM (ROBOt Detection Explosive Materials) system aims to develop a remotely controlled explosive gas detection system handled by a LEGO Mindstrom NXT robot. The main controller has been designed using arduino uno microcontroller. This robot comes with an IP camera for live video streaming, Gas detection system using MQ6 and MQ5 sensors, as well as GPS receiver for live tracking. This robot can be controlled either indoor using Bluetooth or outdoor using the Internet. The system provides information regarding ROBODEM such as sensors results, current location of the robot, current time and date. This system produces an alarm and a popup window appears in the website if there is leakage of explosive gases. ROBODEM has a live tracking of the robot's path that shown in Google map. The prototype has been tested experimentally and the results are analyzed and discussed.
