The robots are here. To become better cooks, you need to distinguish between good and bad food.

A robot chef designed by researchers at Cambridge University has been trained to taste a dish's saltiness and plethora of ingredients at different stages of chewing.

Current electronic testing only provides a snapshot of a food's salt content. Researchers say that replicating the human process will result in a better product.

If robots are to be used for certain aspects of food preparation, it is important that they are able to taste it.

The human perception of taste relies on saliva produced during chewing and digestion, so the concept of tasting as you go is critical.

A robot ‘chef’ has been trained to taste food at different stages of the chewing process to assess whether it is sufficiently seasoned.

The robot chef was trained to make omelettes. Nine variations of scrambled egg and tomatoes were tasted. As the robot prepared dishes, it had a salinity sensor attached to its arm. The team blended the egg mixture and had the robot test the dish again.

For example, it is capable of deciding whether more mixing is needed, or if a dish is too salty.

It's just a single sensor that wouldn't be able to do two different things.

The robotic arms looked similar to those in a car factory, but were made smaller and more affordable to be used in a variety of kitchens.

It's definitely possible, but it's probably a few years away.

The researchers hope to teach the robot to adapt to an individual's tastes, such as preferring sweet or oily food, and become an essential part of households.

The technology will play a major role in homes in the future according to Dr. Muhammad Chughtai, a senior scientist at the domestic appliances manufacturer Beko.

mastication will help robot chefs taste for different dishes and users by using machine- and deep- learning.
