I recently watched a video of the Spring Festival Gala robot performance, and I have to admit, this time the performance truly blew me away. A row of silver-gray humanoid robots performing alongside students from the Ta Gou Martial Arts School, with movements perfectly synchronized, and later even doing front and back flips, soaring 360-degree spins, landing steadily. If I hadn’t seen it with my own eyes, I would really think it was an AI video synthesis.

The underlying technological logic behind this is actually worth a deep dive. The Spring Festival Gala robots are equipped with 360-degree panoramic depth vision and force sensors, capable of capturing stage performers’ positioning and movement rhythm in real time, and even reacting to sudden changes in music. Every movement amplitude, force application timing, and trajectory are autonomously adjusted, which is no longer simple reflexes but decisions based on understanding physical laws.

What’s most interesting is that during flips, the robots need to predict their body posture and center of gravity changes within tens of milliseconds. This involves the cutting-edge “world model” technology — allowing robots to simulate the consequences of their actions in a virtual “mind” before choosing the optimal solution. In simple terms, the robots have gained the ability of “thinking and predicting.”

Even more crucial is multi-robot swarm cooperation. Over twenty Spring Festival Gala robots perform complex formations at high speed, with motion error control within milliseconds. This means that communication latency, coordinated control, and dynamic obstacle avoidance have all reached engineering limits. If a single robot’s flip is a “point” breakthrough, then the swarm performance is a stability validation of the entire system “surface.”

I’ve noticed that this technological progress has potential applications in many fields. In dangerous environments, humanoid robots can perform bomb disposal, reconnaissance in contaminated areas, and other high-risk tasks, reducing human casualties. They don’t need rest, won’t feel fear, and can complete jobs that are difficult for humans in extreme conditions. Plus, with the ability to collaborate with other unmanned systems, sharing data and supporting decision-making, operational efficiency can be greatly improved.

Comparing this to the US approach makes it even clearer. The US military initially chose hydraulic power systems for robot dogs, which resulted in loud noise and difficult maintenance. Later switching to batteries, they faced issues with short endurance and high costs. Take the Q-UGV small robot dog as an example — its maximum range is less than 12 kilometers, and energy consumption increases further under heavy load. In contrast, Chinese robot dogs cost only about $3,000 and have become standard equipment for the PLA. This reflects differences in overall technical routes, engineering, and industrialization.

The collective appearance of the Spring Festival Gala robots indicates that China has already achieved a generational leap from “humanoid mechanical actuators” to “embodied intelligent agents.” This is not only a technological breakthrough but also a comprehensive overtaking in industrialization pathways. In recent years, breakthroughs in artificial intelligence, sensor technology, and materials science have provided a solid foundation for humanoid robot development.

From the perspective of global competition, whoever masters the high ground of humanoid robot technology is likely to take the initiative in future competitions. The performance of the Spring Festival Gala robots is the most direct reflection of this technological strength. For all countries, balancing technological progress with ethical safety will be a long-term challenge. But there’s no doubt that the era of humanoid robots has already arrived, and it’s happening much faster than we imagined.
