How does a hotel robot deliver food to the door of the room?

If the hotel wants to use a robot to deliver food, it will enter the guest's floor and room number into the robot's program, so that the robot will enter the elevator on its own, arrive at the designated floor, and arrive at the designated room. After you arrive at the door, you will be helped to ring the doorbell.

A robot is an intelligent machine that can work semi- or fully autonomously. Robots are capable of performing tasks such as homework or movement through programming and automatic control. The earliest robot in history can be seen in the puppet robot built by Emperor Yang of the Sui Dynasty according to the image of Liu Peng. It was equipped with mechanisms and had the ability to sit, stand up, worship, and fall down.
