The operation modes of the food delivery robot in restaurants are different. For example, Qinglang's food delivery robot just touches his "forehead" to indicate the completion of food delivery, and there is an infrared object sensing system between the three layers of trays, which can intelligently detect the taking status of tray items and realize quick and automatic return.

the p>UI touch screen is simple and easy to use, and can freely realize actions such as starting, stopping, canceling and returning, with outstanding human-computer interaction effect.

The chassis is a general chassis independently developed. Based on multi-sensor fusion technologies such as laser radar+depth vision+machine vision, it can realize indoor high-precision navigation, scan indoor environment in real time, accurately locate and map, and intelligently plan the working route. Any complex environment can move stably and freely for a long time.

the rental price of qinglang's robot is only half of that of the waiter. if it is used for a long time, its service life will be 5-8 years, and it will be paid back in about one year. basically, there are 4-7 years left, and the restaurant has basically invested very little in the service. After this account is calculated, it is very attractive to the service giants such as restaurants, hotels and shopping malls. And overseas markets with higher labor costs should be more attractive.
