Because our country's scientific and technical level is in the stage of development, many places make robots to support and do jobs for people. Among them, the robot that I like the most is the maid robot. They can replace people doing things in the house, giving people more time to rest. It is also not bulky, it has a fairly small area so there is no need to worry about your home space. Or it can also replace the employees in restaurants, factories, ... to deliver food to customers, participate in production, advertise leaflets, ... They have many uses. useful, not just one kind of robot - this robot. I really like them.
