Californian company Skycatch is building drones that will use machine learning to map sites, plan work, and even guide autonomous construction vehicles on building sites. Clear for takeoff: According to New Scientist, over 5,000 Japanese building sites have used Skycatch drones over the past three years to map construction sites. It takes the drones 15 minutes to scan a site and make a map of its terrain--a process that takes a team of humans several days. A flying foreman: The drones use AI that has been trained on data like labeled aerial YouTube footage depicting different kinds of industrial equipment. That enables them to study footage of a building site as they fly overhead, determine where vehicles are, and suggest how they should be moved.
