Humanoids are robots designed to mimic human form and behavior, integrating artificial intelligence to learn, communicate, and perform complex tasks. They are used in industries, healthcare, and entertainment, automating dangerous or repetitive jobs. While not meant to replace humans, they complement human work. Companies like Tesla and Hanson Robotics lead their development, though ethical concerns about privacy and employment arise. In the future, humanoids will be valuable allies in various fields, always under human supervision.
