The future, when advertising will haunt passers-by and look into the windows of skyscrapers, has arrived. Regional provider NTT Docomo will unveil a concept of a multicopter-based mobile display during the Niconico conference in Chiba, Japan this Saturday. A small spherical information screen that can fly anywhere and show something interesting to all people at once.
Structurally, this is a powerful quadcopter with a special frame that forms a sphere with a diameter of 88 cm. It acts as a chassis for the screen, which is formed by strips of LEDs moving in a horizontal plane in a circle. The engineers selected the speed of rotation of the structure and the blinking of the LEDs in order to create a static picture in certain areas of the sphere. Or dynamic - the screen is a screen, you can display whatever you want on it.
The screen resolution is small, 144 by 136 pixels, and then only in the area of the "equator" of the sphere. And this is very good for the first model, because the main task was to achieve a controlled movement of air flows through the structure. Although it is hollow in nature, the moving strips of LEDs form a barrier in the path of air, while the quadcopter's propellers are inside the sphere. It is still difficult to increase the number of LED pixels without affecting the aerodynamics and weight of the car.
Docomo says its 3.4kg machine is highly maneuverable and has a battery life long enough to be used in outdoor public areas. The field of application is the broadest, you can display any useful information, advertising or just funny pictures on the screen. And if you collect a fleet of drones, then you can arrange an air show, in which each "actor" will not be a faceless "flashlight with a propeller", as it is now, but a separate three-dimensional object.
