Development of Microcontroller Based Mobile Gas Sensing Robot

摘要

This paper presents the development of a microcontroller based mobile gas sensing robot. The purpose of the robot is to automatically detect gas leakage along a gas transporting pipeline. The developed microcontroller based mobile gas sensor robot is also proposed to reduce the workload of inspection and maintaining gas pipeline. Pipeline gas detection is difficult as it is odourless but very flammable and the pipeline may run thousand kilometres. The combustible property of LPG gas leads to mass destruction of properties and human casualties. The developed mobile gas sensing robot has shown it capability to detect the LPG gas upon a leakage using its LPG gas sensor and also capable of determining the location of leakage from its Ultrasonic sensor. In addition, the robot is capable of traversing the pipeline back and forth without any human intervention. The experiment has shown that the mobile gas sensing robot can acts as a precautionary measure from gas leakage along a pipeline.
