Laughing my head off! The humanoid robot sports meeting is full of hilarious and chaotic scenes. Come on, everyone, let's take advantage of the chaos and join in the fun!

Oh my god! At the first Humanoid Robot Sports Games, the scene is in complete chaos.

Unitree robots bravely won the gold medal in the 1500 - meter long - distance race, but then they hit another robot and fled the scene (from Douyin @Zaisheng Tongxue).

It's okay that the robots fell into a mess. What's more, a robot that managed to stand up by doing a backward somersault was pushed down again by a human who came to help.

Robot OS: Forget it, I'll just slack off.

Suddenly, the robots in a team started to fight for the ball. Along with their teammates and opponents, they all fell and rolled together.

A boxer suddenly fell to the ground. You might think it was an accident, but actually it was a specially - designed taunting combo - "Back then, with my hands in my pockets, I didn't know what a rival was."

And the Unitree robot in the long - distance race was about to lap its opponent, but it suddenly slowed down and started spinning around the field, making the whole audience burst into laughter.

There are also terracotta - warrior - like robots that even Emperor Qin Shi Huang would exclaim "Oh my god!" if he saw them.

We expected the robot sports games to be lively, but we didn't expect it to be this lively. Who can resist laughing at this?

Moreover, the on - site commentary has completely changed. Instead of using professional sports terms, words like end - to - end, visual recognition, and neural network have become the focus of the commentary.

Unexpectedly, sports commentators now have to brush up on AI knowledge too (doge).

Today is the first day of the first Humanoid Robot Sports Games. Inside the National Speed Skating Oval, hundreds of humanoid robots (maybe half of them are Unitree robots) are competing in various events, such as running, football, boxing, dancing, martial arts, and industrial - scenario applications.

Such a grand event, we came to have a look. While having fun, we also want to see what progress has been made in humanoid robot competitions in the past few months.

Robots Also Have Star Players

We were watching a 5 - vs - 5 football group match. The two competing teams were the Guangchi Team from Beijing Information Science and Technology University vs. the Powa Intelligence Team from the Future Laboratory of Tsinghua University.

The robots used by both teams are of the same model, and the main difference lies in their respective algorithm designs.

The robot players rely on real - time calculation to attack, defend, and cooperate with each other throughout the game. All 10 robots on the field need to recognize each other, distinguish teammates from opponents, and then make strategies.

The on - site game was quite intense. There were often situations where several players crowded together to fight for the ball.

This is also related to the fact that the robots can't pass the ball very far, so it's easy for them to crowd together.

Each team has its own strategies. For example, in the following segment, the red - team players adopted the classic "two - by - two formation" in a 5 - vs - 5 football game, with two players standing parallel in the front and two in the back, forming a square formation.

However, this formation was broken through by the blue - team players. A blue - team player dribbled the ball forward and rushed towards the goal. Unfortunately, the shot missed, and the commentators all sighed in unison.

If a robot player falls due to a physical collision, in some cases, it can stand up by doing a backward somersault and continue the game.

In the first half, the blue - team players were constantly attacking in the front field, while the red - team players focused on defense.

For example, when a red - team player fouled and kicked the ball out of bounds, it would step back voluntarily to follow the rules when taking a throw - in.

The robots' battery life can support several hours of the game. The commentator said that this is different from electric cars. Since the robots are all on the field and don't need to move far, they can be charged on - site even if the battery runs out, so a long - range battery life is not necessary.

Ordinary physical collisions don't cause much damage to the robots. Also, the robots' feet are not customized and are the same as the regular ones. They don't need to wear professional football shoes like humans.

In this game, the star player was the No. 1 player of the blue team, who scored 3 goals for the team. The commentator analyzed that the algorithm of the No. 1 robot might have been specially trained.

There were also many details in the movements. The No. 1 player usually made contact with the ball at a proper position with its feet. When the red - team players tried to intercept, they didn't choose a straight - line route but kept circling. By the time they turned back, the blue - team had already launched an attack.

It's worth mentioning that the red - team players performed significantly better in the second half, showing signs of a comeback. This is a bit beyond general expectations. After all, robot football mainly depends on algorithms. In theory, a better - algorithm robot should always lead. But from the result, just like in human football games, comebacks can also happen in robot games.

The on - site commentator said that every time a robot participates in a game, it means it is having a field - learning experience, which may also have an impact on it.

Of course, there were also quite a lot of chaos on the site.

The goalkeeper ignored the goal and rushed directly to the midfield to join the fight. While the players in the front were still playing, those in the back had fallen in a heap.

Or sometimes, the robots in a team suddenly started to compete with each other. Two blue - team players pushed each other, and incidentally knocked down a red - team player next to them.

This situation might be because two players both recognized the football and wanted to kick it, but the player at the back ignored the one in front of it, so it ended up falling.

There were also times when a robot suddenly froze on the spot. We don't know if it was doing some precise calculations or just got stuck.

The game rules are tailored for robots. In addition to the number of goals, the number of times a robot is dragged off the field manually is also counted. So this time, the busiest thing isn't the stretcher because there isn't one.

The referees and engineers on the field are not allowed to wear white shoes to avoid affecting the robots' recognition of the field boundary.

Finally, the Guangchi Team won the whole game with a score of 4:2.

Robot Boxers Can Taunt

After the intense football game, there was an even more intense boxing match.

We were watching the match between the Zhiyuan Team from Beihang University and the United Team from Beijing University of Posts and Telecommunications and China University of Mining and Technology. They all used Unitree robots. According to the commentator, all 8 teams chose Unitree robots.

The rules of robot boxing are as follows: a simple strike scores 1 point, a heavy strike like a flying kick scores 3 points, and knocking the opponent down and preventing them from standing up independently within 10 seconds scores 10 points. There are three rounds in total. If the scores are tied after three rounds, there will be an overtime.

At the beginning of the game, the two boxers attacked fiercely. A pink - team boxer landed a sweep kick directly on the opponent's torso.

The black - team boxer quickly recognized the opponent's knee strike and made a perfect dodge.

As the game progressed, the black - team boxer seemed to lose its target and started attacking the air like a blind bear.

Later, it was knocked down by the pink - team player. We thought it would lose this round, but when the count reached 9, it suddenly stood up at the last second, creating a highly dramatic effect.

Then there was another exciting exchange of attacks between the two sides. This round ended when the pink - team boxer lost its balance and fell to the ground for 10 seconds.

The commentator also added that maintaining balance is the most important thing in robot boxing competitions.

Finally, this game ended with a score of 75:87. The commentator analyzed that the black - team mainly relied on heavy - leg attacks, while the pink - team scored points by close - range strikes. The two teams had different strategies, and the black - team had a more obvious scoring advantage in the later part of the game.

Since these robots don't have built - in large models, they can't understand the referee's final award - giving ceremony.

The commentator joked on - site that the winning robot should be rewarded with a maintenance service. Fortunately, there is a robot 4S store in Beijing.

The funniest thing is that the winning robot performed a smooth taunting combo: patting its butt and then falling to the ground, just like saying "Back then, with my hands in my pockets, I didn't know what a rival was."

One More Thing

While everyone was using Unitree robots in the competition, Unitree itself quietly won a first place: It won the first place in the 1500 - meter track event with a time of 6 minutes and 34 seconds, which is the first gold medal of this event and also set a world record.

However, it seems that it gave our engineer colleagues quite a hard
