Researchers in British science and technology have realized that housework is not only a simple job like cleaning the floor, but also a complicated job for a family. When there are several robots with different functions and characteristics in the family, each domestic robot is "personalized". In order for the master's instructions to be well conveyed to all robots and fully understood by them, it is very necessary to have a "robot housekeeper", who is responsible for coordinating the division of labor of all robots. test

In order to test their design concept, Kerstin Dautenhahn, a researcher from the University of Hertfordshire in the UK, and her research team members in the film designed a housekeeper robot in a typical semi-detached house in the UK (with two floors and about 10 rooms), which they called "Greta". There are five robots of different shapes and sizes in this house, and there are several other robots handling affairs on Greta's computer screen, which will help the owner to interact with the robots better.

But if the owner only interacts with the robot housekeeper alone, it seems a bit "bound". When they know what kind of robot is working at this time, he must contact the robot housekeeper. In addition, if the owner moves forward, those robots who are engaged in work will ignore them because they receive orders from the robot housekeeper.

In order to solve these problems, the researchers let the robot housekeeper shuttle back and forth between the robots engaged in work during the design process, so the owner can grasp the status of the robots engaged in work at any time.
