Ocado's automated factory has 35 kilometres of conveyor belts
UK online supermarket Ocado has installed more than 35 kilometres of conveyor belts in its Warwickshire factory, upon which crates travel an average of four and five kilometres as items are selected to fulfil customers' orders. While human employees transfer the pre-picked items into customers' order crates, thousands of sensors track the crates' precise location, sending data back to a central control room.

Roaming: These red plastic crates are the workhorses of Ocado's warehouse. Each one travels between four and five kilometres on conveyor belts. They are dispatched to parts of the building to pick up the products that make up each order
