Dawn of the Robo-train: Autonomous railway is the largest robot in the world

The world's largest robot has been unveiled and it is a completely autonomous railway system. AutoHaul has been developed by a mining firm and is being used to transport iron ore from mines to shipping ports 500 miles away (800 km) in Western Australia. This journey can be completed in just 40 hours, including the loading and dumping of the ferrous cargo. Its deployment is the end result of a project which has so far cost $940 million (£740 million). Rio Tinto, the corporation that built the infrastructure and hardware for the locomotive, says this could be the first step in transforming the firm's 1,000-mile (1,700-kilometre) network connecting 16 iron ore mines and two ports.
