Overcooked? Why robotic pizza makers are failing

The "dough feeder". The sauce and cheese modules – even the pepperoni-sprinkler. All lay still.

A now defunct duo of robots were supposed to be churning out pizzas at a Moto Pizza restaurant in Seattle.

However, in May the pair were rendered "basically useless" when their supplier, Picnic, abruptly shut down. , external Technical support for the robots evaporated at that moment, says Lee Kindell, founder and chief executive of Moto Pizza.

He was left wondering what to do with the $160,000 (£118,000), cabinet-like machines and whether buying in pizza bots was really worth it.

"I don't know if I want to do a partnership again because of the failures," he says.

The robot pizza-making business has, it's true, been littered with sorry tales of overcooked promises and melting fortunes. Besides Picnic, other companies that have come and gone include Zume , external and Pazzi, which used , external robot arms to assemble pizzas, as well as Basil Street , external , a purveyor of pizza vending machines.

Although so-called fast food might seem an easy target for automation, it's proved harder than many expected. Plus, bringing robots into pizza restaurants could take away entry-level jobs in the hospitality sector. Is the future really filled with robotic pizza?

"We haven't yet seen any of the success stories materialise the way some people thought they would," admits Sara Senatore, senior restaurants analyst at Bank of America. Her employer has financial interests in multiple high street pizza chains including Papa Johns and Domino's.
