On November 10, 2018, the first China International Import Expo came to an end. In this "world chorus", "black technology" appeared in turn.

Everyone has a dream of flying. Do any friends remember Plike invented by Uncle Wang of "Li Lei and Han Meimei"? At the Expo, there is an advanced version of the "flying car" from Slovakia, which can be called the beauty and sci-fi responsibility.

The most successful super medium commercial helicopter in the world, the Italian AW189 helicopter, also flew to the Expo, with a value of 200 million yuan, which is the most expensive exhibit, and can fly more than 1000 kilometers at most.

Everyone wants to save time and effort. The world's fastest spot welding robot, from Japan, has 12 robotic arms, which are fast enough to be a "thousand hand Guanyin".

This German humanoid five finger manipulator is flexible enough to pick up an embroidery needle.

Big men also have tenderness. Taurus gantry milling is a machine tool for cutting metal. This German man with the largest tonnage practices embroidery, and the positioning accuracy can reach 4 microns.

You can also play the piano yourself. You only need to click on the APP, and the German piano will automatically send out human notes.

Everyone wants to be safe. It is conceivable how high the size requirements of cardiac pacemakers are. At the Expo, this American pacemaker was the smallest in the world, only the size of a coin, 90% smaller than the traditional one.

We all like WiFi, but we don't like radiation. This Dutch light WiFi bulb can provide broadband network while lighting, without radiation problems.

New era, share the future. I hope these "black technologies" will come into our life faster, better and cheaper!
