The device is capable of speaking and changing facial expressions.

Robots move at very fast speeds. And, furthermore, they increasingly resemble humans. This is demonstrated by devices such as Ameca, the most advanced humanoid robot in the world at the Mobile World Congress.

It is a human-shaped robot developed by the British company Engineered Arts, which was presented with great fanfare in the last throes of 2021. The device is capable of moving its arms and legs and also drawing expressions on its face, which, at first glance, appears almost completely human. Almost, because it is gray and there is no skin on top.

Ameca is specifically designed to interact directly with humans. It is not, therefore, a robot designed to transport heavy boxes or carry out surveillance work. Although, it could probably also fulfill these missions. Instead, Engineered Arts suggests that he could work as a receptionist, be a guide at exhibitions and museums, or give talks. Because yes, the robot doesn't just smile or put its index finger on its lips to ask for silence. Also speaks.

The device has artificial intelligence that allows it to interact with those around it by using words. Specifically, the model that is walking around the Barcelona fair has been trained with GPT-4, the same technology that allows the conversational robot.

Ameca also has cameras that allow it to recognize the gestures of the person with whom you are having a conversation. Thanks to them, you can read their expressions and respond correctly.
