Opponents of artificial intelligence (AI) have long predicted the time will come when robots take over the jobs of human employees. That day has arrived, with a number of food service companies using technology in previously human-filled roles.

Reasoning Behind the Shift

Ever since vending machines started to dispense food in 1897, food service automation has gained ground, moving towards self-service and eventually machine services. There are multiple reasons why food service companies are looking for alternatives to the traditional ways of producing and serving food, including:

  • The shortage of kitchen workers, which is a major concern in many areas where hospitality and food service are big businesses. For example, employee turnover in the U.S. restaurants and accommodations sector was 72.9 percent in 2016, according to Restaurant.org.
  • Higher minimum wages that came into force in 19 states during 2017, with other states expected to follow. This factor contributes to a sizeable increase in food preparation and service costs, resulting in higher prices for the customer—increases which in many instances the market is not yet ready to tolerate.
  • Better profitability, which is precipitated by faster delivery and lower costs, and stronger market performance. For example, Dominos stock price rose from $13 seven years ago to over $200 in 2017, partly as a result of its introduction of voice-ordering capabilities and other technology solutions.

All are very good reasons to replace human workers with robotics. A spokesperson for McDonalds cited these as well as the "tremendous" margin of human error, poor hygiene, a lack of education and laziness as additional reasons for the shift towards automation.

Food Services Currently Using Robots

Here are some great examples of the progress made towards the use of food producing robots:

  • Sally the Salad Maker is a robot making real inroads into food production, specializing in salads. Sally is about the size (and shape) of a dorm-room refrigerator, and can deliver up to 1,000 different types of salad in 60 seconds while you watch. The robot uses 21 pre-prepared ingredients and can create salads based on extremely precise caloric information. Sally is the brainchild of Chowbotics, Inc., for whom HVS is currently conducting a candidate search for the position of VP Sales.
  • California's Miso Robotics has developed an AI kitchen assistant named "Flippy" who helps with grilling, frying, food preparation and plating. It has software that integrates with sensors and cameras that enable it to "see" the food and handle functions like temperature control.
  • American food service companies aren't the only ones interested, either. Fanuc in Japan uses robots to cook and serve four types of noodle bowls in 90 seconds, which sell for the high price of $10 each.
  • The Wall-E restaurant in China's Hefei Anhui province has a robotic workforce of 30 4-foot high units that take orders, cook, bake and serve by moving along tracks in the restaurant. The robots don't do any cleaning, however—that is left to the humans!

Other technological applications in the industry include Eatsa, a Silicon Valley-based chain of quinoa-only restaurants, which uses iPads in place of cashiers and servers and pops out food orders from a wall of high-tech cubbies, and McDonalds, which plans to spend more than $50,000 to install self-ordering kiosks and launch improved mobile app ordering and payment options at 20,000 restaurants in 2018.

Benefits to the Food Service Industry

The shift to food producing robots offers substantial benefits for the industry. Since some states have a major shortage of kitchen workers, the ratio of demand to supply has caused compensation costs to soar. In the San Francisco Bay area, for example, a line cook costs around $40,000 a year. Robots, however, don't require sleep, don't take vacations and hardly ever get "sick." Apart from the obvious advantages of reducing employment costs, other labor-related benefits include the elimination of:

  • Vacation and sick leave absences
  • Workplace concerns, such as personality conflicts and unfair labor practices
  • Training costs and poor education problems
  • Lower number of human errors

In addition, we can expect to see robot use resulting in less waste and safer food handling procedures, both of which are critical issues for the 21st century.

Looking to the Future

Food producing robots certainly seem to have a brilliant future, given the multitude of potential markets for them. The creators of Sally, for example, have a grand vision for her, according to Bloomberg. They are hoping to see her installed in hotels, convention centers, airports and gyms—wherever visitors check in late or room service is less than efficient.

Fast food chains will be able to exponentially increase their menu offerings, as well as adding healthier options with very little additional labor cost or other factors. Most types of robotic food preparation still require a component of human interaction, which fact offers entrepreneurial opportunities in itself.

Counting the Costs

At this point in time, robotics are not cheap. The restaurant version of Sally the Salad Maker currently costs around $30,000, although lease opportunities are available. The Wall.e's workforce comes in at $10,000 per robot, and while Flippy is touted as a "$0 an hour" worker, obviously that is not the whole story. Whatever the cost, if food companies and restaurants compare it with labor costs, wastage, theft and other expenses, the investment begins to look very attractive.

It stands to reason some sectors of society will be unhappy about the idea of robots taking over human occupations, but even while Sally's design makes human salad makers obsolete, it creates new jobs for food preparation workers.

A New Revolution

There's a new revolution taking place in food production and service, which includes complex processes such as preparation, cooking, delivery and serving. Robots are already routinely used for many of these tasks, and in activities where speed, consistency, sanitation control and high levels of repetition are required, they almost always beat human workers in terms of efficiency.
