AI is becoming more and more common in our life. Not long ago, an AI canteen opened in Shanghai. The AI canteen, located in the Hongqiao Area, covers about 13 m2. It can serve about 300 people every day, and most of them are old people living nearby or office workers in the area.
At the canteen people need to order food on a screen. For those who are not sure what they want to eat, the canteen's cooking system can give advice.
The canteen's robotic arms cook dishes. They can make different kinds of Chinese dishes like noodles, gongbao chicken, and so on. What's more, the robotic arms can pack dishes and control the temperature for dine-in or takeaway.
People simply need to put their dishes on a smart cash desk and the system will tell them the price of the meal. People can pay in different ways, like using bank cards or QR codes (二维码). The prices of the food at the AI canteen are pretty good. The meat dish costs 8 yuanwhile one vegetable dish costs only 3.5 yuan.
"The meals cooked by robots taste as good as those cooked by humans. it is cheap and convenient for us to eat in the AI canteen," said an old man.
