The United States has developed a robot with expression

James Hansen, a doctoral student at the School of Interactive Arts and Engineering at the University of Texas at the United States, recently developed the K-BOT, a robot that can make 28 expressions. It can not only smile nicely to people, but also make ridicule, frowns and other unfriendly expressions.
The K-BOT currently has only a head: it has soft, natural-looking skin, high cheekbones and large blue eyes. The robot observes the human facial expression through a camera installed in both eyes, and analyzes the captured image through an internal software system, and then controls the facial artificial muscle by 24 small engines installed in the head to be surprised. Happy or sad, etc. respond to different expressions.
The weight of the K-BOT head is 2 kg. K-BOT's "skin" is the most expensive, and its raw material is synthetic rubber and foam. It was modified in Hanson's laboratory. It is flexible and very similar to human skin.
The human face has evolved for millions of years and has become able to express emotions very well. Even newborns can see the emotions expressed by others' faces. In Hanson's view, this point makes the creation of robots with similar human expressions of great significance. Although humans have invented robots with many uses and shapes, robots with vivid human expressions such as K-BOT made with cutting-edge technology are the first ones. Hanson said: "K-BOT is not the world's most expensive robot, but in terms of the complexity of what it does, it is the most technologically advanced robot in the world." According to reports, before the K-BOT robot "an Di" can only imitate 4 kinds of facial movements.
