This was stated by scientists of the Japanese company DrinkShift, which showed their development at the electronics exhibition in Las Vegas. 
Behind the words of the inventors, the refrigerator is equipped with the intellect, works “in conjunction” with a mobile phone and ensures that the beer stocks never run out. The robot refrigerator monitors the number of remaining bottles and orders new bottles on its own, taking into account the preferences of the host in the intoxicating drink.
The slogan of the mini-bar was: "We have created a world in which you will never run out of beer."
