“Clearly, an efficient method for detecting and repairing damaged pipelines is overdue. Engineers based out MIT’s Mechatronics Research Laboratory have been developing a concept that might fit the bill. … Normally leaks are detected by acoustic sensors above ground, but the MIT team and their partners at King Fahd University of Petroleum and Minerals have designed a self-propelled robot that will be able scoot around inside the pipes.”
