Designing a wheeled robot model for flammable gas leakage tracking

摘要

Gas pipeline tracking to find flammable gas leakage could be done manually by human worker. The activity are including walking from the start point along the way gas pipeline and record the condition. If the worker detects the presence of flammable gas, usually by its smell, and found the leakage point, he or she will stop and raise a concern for surrounding people or report to the office for further actions. This activities could harm the worker especially there will risk of fire and probably endangered life. The main objective of the research was to provide a model of intelligent gas pipeline tracking and to know its performance. The result of the research is a wheeled robot model developed based on the Arduino microprocessor equipped with gas sensor MQ2, LED and buzzer alarm for alert people and data logger in microSD memory card. The test results showed that wheeled robot able to sense the presence of flammable gas, tracking the gas pipeline using line follower principle, found the leakage point and stop instantly around 5.87 cm from the leakage point, as well as record the data in the form of file namely DATA.txt which can be used for further analysis.
