In the performance, two naive giant pandas were impressive. They are all messengers of culture, representing the inheritance of China's "national treasure" craft. It is understood that the panda props come from the craftsmen of Sichuan Nanchong Puppet Theatre, who have been committed to protecting and inheriting this national intangible cultural heritage of China.
Puppets need to be worn by people to perform, so they need to weigh less than 30 kilograms. According to Tang, director of Sichuan Nanchong Puppet Theatre, this requirement alone kept their team awake for several nights.
In order to achieve the expected results, the production team tried a variety of materials such as artificial paper rattan, natural white rattan, bamboo strips, aluminum alloy wires, carbon fiber strips, PVC imitation rattan and so on. After hundreds of experiments, the production process of LED lamp with aluminum alloy tube and carbon fiber strip was finally determined.
The final version of the panda prop is 2.35 meters high, but it weighs only about 20 kilograms, which is dozens of kilograms lighter than the original version. Even Tang couldn't help feeling, "I didn't expect everyone, Qi Xin, to work together to make such a high-tech, light-weight big prop that can achieve the performance effect at the same time."
Ice screens and robots come from domestic teams.
On the stage, 24 screens present a beautiful image of China in the new era. These almost transparent screens have a nice name: "Ice Screen". This innovative design, which originated from China, can realize transparent image display, and has won many invention patents at home and abroad.
Huang Qingsheng, head of the "Ice Screen" R&D team and director of the Beijing-based cultural performance project of Shenzhen Yipin Radio and Television Co., Ltd., said that in order to participate in the 8-minute performance, the team upgraded the process. "This time, we made a three-meter-long screen with no beams in the middle. This technology should be the first in the world at present. "
Carrying the "ice screen" out of the gorgeous dance steps are 24 flexible mobile robots. According to Zhang Lei, head of the robot R&D team and president of the mobile robot division of Shenyang Song Xin Robot Automation Co., Ltd., two technological breakthroughs have been achieved this time: First, the robot navigation is more accurate. "There are frequent shuttle interactions between actors and robots, and there are many lights in the performance venue, which requires robots to see far and clearly." Secondly, compared with the commonly used industrial robots, the movements are more complex and flexible, including rotating and swinging during the journey.
Zhang Lei said that it took the team only two months from deciding to participate in the performance to starting the rehearsal, and all the members worked day and night before finally customizing the robot that could participate in the performance.
Graphene clothing can be heated for 4 hours.
On the day of the closing ceremony, the average temperature over the years was-10 degrees Celsius, and the wind force was about 5. The cold wind is a big challenge for the whole performance team. In order to do the actor's cold-proof and warm-keeping work well, the main creative team adopted graphene smart heating clothes to ensure the actor's elegant movements and prevent frostbite.
Graphene is an ultra-new nano-material, which has ultra-high strength and high thermal conductivity, and is praised as "the king of new materials" by the industry. Using the characteristics of graphene, researchers in China developed ultra-thin transparent graphene electrothermal film technology, which was used in the manufacture of smart devices, and applied for patent protection abroad.
"Actors' costumes are required to be light and flexible. At the same time, whether it is the rehearsal venue or the closing ceremony of Pyeongchang, the weather is very cold, and graphene clothing can play a good role in insulation and heating. "Li, head of the graphene team and Shenzhen New Materials Technology Co., Ltd., said that clothing can also be adjusted according to environmental requirements." At the beginning, our design requirement was to keep heating at MINUS 5 degrees Celsius for 8 minutes. Later, considering the waiting time and other factors, it was adjusted to MINUS 20 degrees Celsius for 4 hours. "
At the same time, in order to make the "ice screen" and the robot run smoothly, the main creative team also specially tested the equipment for cold resistance and wind resistance.
