This document describes an IOT gas pipe leakage detector robot. The robot clings to the outer surface of gas pipes and moves along the pipe to detect any gas leaks using an onboard gas sensor. If a leak is detected, the robot uses GPS and IOT to transmit the location of the leak. The robot is designed to detect leaks in gas pipes automatically and at low cost by moving continuously along the pipe. It consists of components like a Raspberry Pi, gas sensor, GPS module, and uses Python software.
