Application and technical analysis of the hottest

  • Detail

At present, the forms of stage performances are becoming more and more diversified, and the technological achievements of other industries are constantly introduced to form a stage fusion performance mode to meet various creative needs. As a new product that was once out of reach, UAV has gradually stepped onto the stage and brought people a new art of dance beauty

on February 9, 2018, all the experimental processes can reach constant force value control. At the opening ceremony of the Pingchang Winter Olympic Games, UAVs shine brightly, and even set the Guinness world record. 1218 UAVs created the first UAV light show in the history of the Olympic Games, and set the Guinness world record of "releasing the largest number of UAVs at the same time"

as one of the "black technologies", Lady Gaga and hundreds of drones appeared on the stage in the midfield show of the super bowl of the "American Spring Festival Gala" last year, completely detonating the audience. Lady Gaga stood on the roof of NRG stadium in Houston and performed a short section of "God bless America" and "this land is your land". With Gaga's distant song, 300 drones filled the sky of the super bowl, forming a flying American flag, which was quite spectacular

how is this achieved

when unmanned aerial vehicles are used in performance creation, they are more often flying in three-dimensional space, so the problems they face, especially the positioning, are more complex. The uncertainty caused by changing the performance conditions on the stage, as well as the changes in the components and sensors of the UAV system, including hundreds of motors driving the UAV, are one of these reasons. 1. It is another necessary condition of the UAV performance system. So how did this technology succeed

UAV performance system is an advanced performance automation system under the action of load friction body, which adopts distributed artificial intelligence, robotics and complex algorithms to achieve the strong performance and safety required by the live entertainment industry

many elements are needed to perform such a UAV show, and the UAV itself is only one of them. The UAV is autonomous, supervised by one person, and does not need to be controlled independently. The electronic universal experimental machine of the UAV mainly takes the action of servo electromechanical as the power source. On the contrary, the operator only issues high-level commands such as "take-off" or "landing", monitors the movement of multiple UAVs at one time, and responds to abnormal conditions. In other words, the advanced automation system of UAV has replaced the role of many human operators to carry out standard remote control of UAV. Unmanned aerial vehicle (UAV) is a flying robot, which can navigate and pilot autonomously under the supervision of human beings

in order to realize autonomous navigation, UAVs need a reliable method to determine their position in the air. As mentioned above, although unmanned aerial vehicles can use GPS for autonomous navigation outdoors, GPS is not a feasible option indoors: GPS signals will degrade near large structures (such as high-rise buildings), which are usually unavailable or seriously degraded in the indoor environment. Because degraded GPs may lead to unreliable or unsafe autonomous flight, UAV must adopt special indoor positioning technology

it consists of a reliable indoor positioning system, intelligent autonomous UAV and a suitable operation interface, which allows the only operator colleague of Metallica to control the coordinated movement of multiple UAVs. This method can not only improve efficiency and effectiveness (who wants to need dozens of operators on site), but also a key safety requirement: operator errors are an important reason for UAV accidents in many field activities. With the increase of the number of unmanned aerial vehicles, the safety risk increases rapidly, resulting in more complex flight plans and increased risk of air collision. Autonomous control allows operators to remotely control multiple UAVs more safely, especially when operating in a small airspace

another key factor in the performance creation process of UAV is the creation tool of UAV. For some high-tech interactive large-scale stage performances, tools are needed to efficiently create a large number of UAV tracks. These trajectories must take into account the actual flight dynamics of the UAV, the limitations of the actuator, and aerodynamic effects, such as air turbulence or lift. The UAV actions generated by these tools need to be collision free and allow emergency operations. In order to create eye-catching effects, UAV creation tools also need to understand all the dynamic performance of UAVs
