As part of their trip to the Lego factory in Denmark, Gizmodo have made a video showing one of the gigantic warehouses that stores the Lego bricks prior to decoration and boxing. There are four warehouses, dubbed cathedrals by Gizmodo, that store 900 million pieces at any given time. They are over 65ft high and cover 65.6sq/miles. Inside each cathedral are four robots that whiz around at up to 2.5 metres per second collecting boxes. The impressive operation is completely automated.
