KEY TAKEAWAYS
- A humanoid robot scored a free kick before performing Cristiano Ronaldo's famous "Siuuu."
- The viral moment came during the World Humanoid Robot Games in Beijing.
- More than 2,000 robots from 16 countries are competing across 51 events.
The clip, shared widely on social media, shows the robot completing the football demonstration before jumping and landing with its arms spread in a pose instantly recognisable to football fans around the world.
This robot scores the free kick.

Ronaldo's 'Siuuu' reaches the world of robotics
Ronaldo's celebration has become one of football's most recognisable gestures since the Portuguese star popularised it during his playing career.Its inclusion in a humanoid robot demonstration is more than a novelty. Reproducing the celebration requires the machine to coordinate a sequence involving jumping, body control, balance and a controlled landing.
Those physical movements are central to the broader purpose of the 2026 World Humanoid Robot Games, which are designed to demonstrate how far humanoid robotics has progressed in areas such as movement, coordination and interaction with the physical world.
The football demonstration was one of several eye-catching displays during the competition, with robots also taking part in events ranging from sprinting and high jump to table tennis, boxing and football.
More than 2,000 robots take over Beijing
The second World Humanoid Robot Games officially opened at Beijing's National Speed Skating Oval, also known as the Ice Ribbon, on Saturday.The five-day event runs until 26 August and features 666 teams and 2,056 robots from 16 countries and six continents. Organisers have scheduled 51 events, covering both competitive sports and scenario-based tasks intended to test how humanoid robots perform in more practical situations.
The scale of the event has increased substantially compared with its inaugural edition in 2025.
The opening ceremony also featured more than 1,000 humanoid robots showcasing different capabilities, under the theme "Intelligence Competing Toward the Future."
Beijing puts humanoid robots through their paces
The Ronaldo celebration is amusing, but the more serious story from Beijing is the rapid improvement in robotic athletic performance.A humanoid robot called Tiangong Ultra, developed by the Beijing Humanoid Robot Innovation Center, completed a 100-metre preliminary heat in 9.39 seconds.
That was faster than Usain Bolt's human 100-metre world record of 9.58 seconds, set in Berlin in 2009. Another humanoid robot, Honor's Lightning, recorded 9.47 seconds in the competition.
The achievement, however, should not be described as a new official human athletics world record. Robotic competitions operate under different conditions and are not governed by the same rules and standards used for human track-and-field records.
The performances nevertheless show how quickly humanoid locomotion is developing. The robots also revealed one of the technology's current limitations: after completing the sprint, some lost control and crashed into barriers near the finish.
From viral celebration to serious robotics development
The "Siuuu" moment may look like little more than a clever publicity stunt, but it reflects a broader shift in what humanoid robots are being asked to do.Rather than simply walking or carrying objects, the machines are increasingly being trained to perform sequences involving balance, speed, coordination and rapid changes in body position.
That makes sport particularly useful as a testing environment. A football pitch provides a relatively clear way to measure whether a robot can move accurately, react to its surroundings and maintain control whilst performing demanding physical actions.
The World Humanoid Robot Games are therefore becoming more than a spectacle. They are also a public demonstration of the progress - and remaining weaknesses - in humanoid robotics.
