Why online supermarket Ocado wants to take the human touch out of groceries

(CNN)In a warehouse larger than three football fields, 3,000 bots scuttle along at 13 feet per second, swerving to avoid each other in a complex dance governed by artificial intelligence. Their goal? To get your groceries much faster than humanly possible.

The south-east London warehouse is run by British online supermarket Ocado and features the latest in its automation technology. The company started out developing the Ocado Smart Platform (OSP) for its own use, but the system has proved so successful it licenses it to other supermarkets.
