Super giant can wear ice skating panda puppets, robot can be arranged to complete their movements, graphene can be warm and warm smart clothing ... ... 25 evening, at the closing ceremony of the PyeongChang Winter Olympics, 'Beijing eight minutes' amazing Appearance, a variety of cutting-edge high-tech to help them show the best results.
That evening, as the host city of the next Olympic Winter Games, Beijing, China, has brought a unique eight-minute performance to the world, and Zhang Yimou, who is good at using the grand performance of 'human-sea tactics' At the same time using a variety of scientific and technological means to present more unique ideas.
During the performance, two naive panda puppets were impressive: the two oversized puppets were worn by men and weighed less than 30 pounds, so the team made a try out of hundreds of innovative materials Test, and ultimately determine the combination of aluminum alloy pipe and carbon fiber, with the LED lamp on the production process.
At the same time, in order to overcome the problem of 'acclimatization' in different environments, the production team constantly debugs to upgrade and improve the process.The final version of the Panda puppet props, 2 meters 35, weighs only 20 pounds, a few lighter than the initial version Ten pounds.
On the stage of "Beijing eight minutes", 24 big screens showed the beautiful image of China in a new era and became a highlight of the performances. These almost transparent screens, called 'ice screen', originated from the innovation in China Design, you can achieve transparent image display, so that the effect is more agile, has won a number of invention patents at home and abroad.
According to the 'ice screen' R & D team leader Huang Qingsheng introduced to participate in this performance, the team conducted a technical research, simultaneous upgrading of the process to upgrade, 'made a three-meter long screen and there is no beam in the middle, this process is currently In the world should be the first one '.
During the performance, 24 mobile robots with "ice screen" jumping out of the gorgeous dance arena, which flexibly interact with roller skating dancers, crossing from Pyeongchang to Beijing in 2022. This is the first time that a new generation of intelligent robots in China has been held in the international The event performed difficult dance moves, which not only completed its own movement arrangement, but also with the actors, the ground projection linkage performance, to achieve the upgrading of technology innovation.
'Beijing eight minutes' is at 21:18 local time in Pyeongchang, the temperature dropped to about minus 3 degrees. In order to do a good job in the work of anti-cold warm-up of the performers, the creative team used graphene smart heating clothing to ensure that the actors in the action Smart and beautiful at the same time will not be frostbite.
Graphene is a new type of nano-materials, with ultra-high strength, high thermal conductivity, the industry as the 'king of new materials.' Utilizing its characteristics, Chinese researchers developed a thin transparent graphene electrothermal film technology, Used in intelligent equipment manufacturing and applied for patent protection.In order to ensure the success of the performance, the research team conducted a live experiment under the condition of simulating minus 20 degrees, while ensuring that the heating effect meets the requirements, while making every effort to ensure material safety, battery life and Costume comfort.
In cold weather, in addition to the performers who need to keep warm, there are all on-site performance equipment. In order for the 'ice screen' and the mobile robot to run smoothly in Pyeongchang, the creative team specially tested the device for low temperature resistance and wind resistance According to the test results continue to optimize the performance of equipment to ensure its stability in the cold, windy environment.
According to the introduction of the creative team, during the rehearsal of the performance, 'OpenGL Performing Aid Training System' and 'Beijing Eight-minute Art Performance Rehearsal System' organized by Beijing Institute of Technology and Beijing Film Academy have been serving as directors 'eyes and' These two systems can simulate the whole process of theatrical performance according to the creative plan of the director, and show the movement track, location information, formation change and movement speed of the performer in various forms such as visual interface, drawings, videos, etc., Help directors to control, make decisions and improve performance programs, thereby greatly improving rehearsal efficiency.
