Humanoids are robots or artificial beings designed to resemble humans in appearance and behavior. They often have a human-like shape, including a head, arms, and legs, and may be programmed to perform tasks or interact with people. Humanoids can be used in various fields, such as healthcare, education, and entertainment. These robots can vary in complexity, from simple machines that mimic basic human movements to advanced systems equipped with artificial intelligence. Some humanoids are designed for research purposes, helping scientists understand human behavior, while others serve as companions or assistants in everyday life.
