In 2025, engineers in China showed off a walking robot shaped like a person, with dozens of moving joints that let it stride across a stage almost like a human model.
A humanoid robot has a head, arms, and legs arranged like a person's, with joints letting it bend, step, and balance similarly to a human. Engineers build robots this way to move through spaces made for people.
A kite is a simple flying toy held up by wind and string, with no joints or human shape. A whistle just makes a sound when blown, neither related to human-like robots.
Building a robot that walks on two legs is one of the hardest engineering challenges, since it must constantly adjust balance without thinking.
