CCTV News: What does it feel like when the enthusiastic Northeast Yangge meets a humanoid robot with a sense of technology? Humanoid robot dance is one of the most eye-catching programs on the Spring Festival Gala stage this year. How does robots "raise" dance for yangko actors? Follow the reporter to find out.

Robot handkerchief? The Black Technology Revealed on the China Taiwan Spring Festival Gala

On the stage of this year's Spring Festival Gala, wearing a red flower jacket and a red handkerchief, the Northeast Yangge with a technological style, lively and funny. Zhang Peng and Li Mengyu, who are in charge of choreography, were dance directors who were responsible for the Kashgar branch of the Taiwan Spring Festival Gala last year. Even the choreographer needs to practice yangko for a long time. Is it difficult for humanoid robots?

Yushu Technology Engineer Zhang Yangguang: We have specially prepared a function of directly generating actions (programs) from videos for this Spring Festival Gala program. We can compare the actors' movements and directly map the robot's movements frame by frame. In this way, the direct export (program) can be placed on the robot and moved directly.

The dancer's movements in front of the camera are carefully captured by the AI ​​software to form command codes, and then finely adjusted by the engineer. The big model greatly improves the robot's learning efficiency. During this yangko performance in the Spring Festival Gala, the robot team prepared more than 130 dance moves. All 19 joints of the humanoid robot during the performance must be carried out to carry out large-scale movement, which is a test of the reliability of the robot. In order to make the robot more vivid and lively on the Spring Festival Gala stage, the engineers also designed a small detail - making the robot a "trick".

Zhang Yangguang: The first point is that the audience does not know that there is this skilled handkerchief, because when you see the skilled handkerchief, you will know that it will turn. We don’t want the audience to know that it will turn in advance, so we need to put it on with a black sleeve first. In this way, the audience actually only looks like there is a handkerchief. It is not a skilled handkerchief. The audience does not know that it will turn. Then during the dance process, we will combine this machine with a mechanism behind us, generate a downward force, break it off by itself, and reveal this skill handkerchief. Once the motor rotates again, the handkerchief can rotate and rotate at the same frequency as a human.

The wonderful resonance between "Ruyi Change" technology and Chinese aesthetics

In addition to the robot with full technological style, the stage style of this year's Spring Festival Gala has also attracted much attention. The stage is like a "resolute wish", which fills the immersion and interaction of the Spring Festival Gala party, and also conveys the joy and blessing of everything.

Jiang Yuhao, Visual Director of the Taiwan "2025 Spring Festival Gala": We went to find the "ruyi" in Chinese traditional culture, whether it was looking for patterns or cultural relics. In the end, we chose a handful of gilded silver "ruyi" unearthed from Famen Temple in Shaanxi to extract the earliest handful of gilded silver "ruyi" in China as the starting shape for our reference to "ruyi".

The emergence of Ruyi's style breaks the traditional "onstage" stage and "offstage" audience. Actors can walk on the Ruyi channel and stand in front of Ruyi's back screen to perform. In addition, the most eye-catching thing in this year's Spring Festival Gala dance is the presentation of naked-eye 3D effects on the real scene stage. With the application of technologies such as 5X5 cubic ground screen, strip screen matrix, AR virtual and variable light columns, programs such as "Welcome to Blessing", "Yi Ren", "Board", and "Happy on the Branches" that combine modern and traditional visual styles can collide with the wonderful resonance between technology and traditional Chinese aesthetics in the "Ruyi Change".

Jiang Yuhao: Combining our contemporary light and shadow art, visual art and various modern tracking technologies, we have completed a more modern artistic performance, which can make traditional culture shine with fresh vitality and allow more friends to understand the charm of Chinese traditional culture.
