IoT is happening at Amazon's fulfilment Warehouses

Amazon's drones have a long way to become reality, but the real magic of the Internet of Things (IoT) is already happening at Amazon's vast fulfillment warehouses in the US. 

Amazon runs a fleet of thousands of small robots moving storage pods around so orders can be fulfilled in record time. They are so efficient that they can move an entire warehouse and have ready to operate again during the weekend. All together the small robots have travelled over 93 million miles — almost the distance from Earth to the Sun.
