Food delivery robot debuts in Shenyang
My name is Liangliang, I am from Shenyang, and I am happy to serve you.
When I walked into a seafood bar on Jihong Road in Tiexi District on March 1, I was greeted by a robot, which made the customers extremely happy. This is the first robot restaurant in Shenyang.
At the restaurant, a silver-white robot with a height of approximately 1 kilogram and a weight of about 10 kilograms walked directly to a dining table carrying several plates of food. It stayed there for about a minute. When the customer took the dishes to the table, the robot went straight to the place where the food was received. While traveling, if it encounters a person blocking the way, it will send out "You are blocking me, please get out of the way". After the person misses it, it will arrive at its destination and wait for the next instruction to arrive.
Liangliang does not need a navigation bar on the ground, and can walk freely between dining tables within a meter length range. Liangliang can say hello, please eat, goodbye and other common phrases.
From one table to another, Liangliang served beer and various dishes to the guests. As this is your dish, I wish you a happy meal and goodbye. Liangliang made a beautiful sound, and the customers laughed knowingly. Liangliang interacts with customers with four expressions including smile and sadness. After a while, it automatically walked to the charging pile and started charging. Liangliang has a power detection function. When the power is low, you can go to the charging position to charge.
