Low cost in-pipe leak detection robot

Abstract

In this paper we work towards a new prototype for an inexpensive in-pipe leak detection system. Our proposed robotic system is able to detect leaks in pipes in a reliable and autonomous fashion. The robotic system inspects the network and sends leak signals wirelessly. The detection principle is based on the presence of a pressure gradient in the neighborhood of a leak in the pressurized pipe. This pressure gradient is translated into force and hence a displacement by means of a lever which comes in contact with a conducting core to produce a signal. Length and shape of the lever are changed to study the change in sensitivity. © 2016 IEEE.
