This document describes the development of a prototype pipe tracking robot that uses electronic nose technology to detect gas leaks. The robot is designed to automatically track and follow pipes using ultrasonic sensors. It also uses an MQ6 gas sensor to detect the presence of gas leaks, identify the type of gas, and transmit sensor data to an Arduino microcontroller and LCD display. The researchers tested the prototype's ability to track a PVC pipe, detect different gases, and display detection information. Test results showed the robot could successfully track a 10 cm diameter pipe from 5 cm away and detect gas leaks within 1 minute. The LCD also correctly displayed gas detection information.
