Robots that can clean train carriages and drones to inspect railway bridge arches are being developed by scientists in two new research projects.The Heriot-Watt University researchers are working onrobotised mobile inspection platforms that can operate in hard-to-reach areas such asbetween and under the seats of a train carriage.The robot platforms will detect hazards using an innovative algorithm and pick up rubbish such as discarded newspapers as well as dangerous items such as needles and blades.The second project will develop autonomous drone technology to inspect railway bridge archways, particularly the inner curve which is difficult to access.
