A fire at the flagship robotic distribution centre of British online supermarket pioneer Ocado is now under control but has badly damaged the complex, the fire service said on Wednesday.
Around 20 fire engines and 200 firefighters were called to the highly automated site in Andover, southern England, at 0244 GMT on Tuesday to tackle a blaze that raged for over 24 hours, prompting part of the roof to collapse.
The Andover plant, which can process 65,000 orders a week, is Ocado's third automated warehouse and has been instrumental in the firm winning four major deals to sell its technology to international retailers such as U.S. group Kroger Co and France's Casino.
While Ocado's first two centres required humans to load thousands of crates traveling on miles of conveyor belts, Andover has hundreds of robots speeding along at four metres per second on giant grids.
Ocado said on Tuesday the fire had broken out on one of the grids of robots, forcing it to suspend operations.
