These robots will one day roam our sewers

The UN states that by 2025, two thirds of the world's population may face water shortages, leading to the displacement of 700 million people. So are we doing enough to conserve and protect our most precious resource? A new solution is on the way - The Pipebots project is a collaboration between four major UK universities, to design and build miniature autonomous robots that can travel the underground pipe network to check for leaks and damage. RAZOR heads to Sheffield and Leeds to see the Pipebot robot prototypes in action.
