Some fast-food companies have begun experimenting with robotic technology that would considerably reduce the employment of restaurant workers who are currently protesting against the corporate chains demanding higher wages.

The Employment Policies Institute, an organization that backs corporations, released an ad last year in The Wall Street Journal that warned a sharp increase in the minimum wage would force restaurants to cut jobs in exchange for automated services, according to CNN Money.

"Faced with a $15 wage mandate, restaurants have to reduce the cost of service," the ad read. "That means fewer entry-level jobs and more automated alternatives -- even in the kitchen."

However, other experts in the restaurant and hospitality industry said they believe any switch to these new technologies would take time and that human interaction is important to those industries.

A number of establishments such as Panera Bread, Chili's and Applebee's have already announced plans to implement the new automated technology into their stores, CNN reported.

Last month Panera announced that within the next three years its stores will include self-service ordering kiosks and a mobile ordering option. The company spent $42 million to develop the new system but insisted that it would not cut any jobs.

Chili's and Applebee's have made plans to have its tables equipped with a tablet so customers could order their food and pay for their meal without having to speak with a human server.

The University of Oxford researchers released a study last year that stated there is a 92 percent chance the fast-food and serving industry would turn to automated systems in the next few decades.

Even delivery driver jobs are expected to become obsolete in the coming decades as self-driving cars are being developed and perfected. IBM's Watson platform is already improving artificial intelligence technology, making it easier to interact with humans.

According to the Oxford research report, start-up companies have begun marketing robots that can bartend and prepare gourmet burgers, and a food processing company in Spain has already started to use robots to inspect heads of lettuce.
