Which Doraemon gadget is the most powerful? Some of them have actually come true

Speaking of "Doraemon", I believe that all of you are familiar with it. "Doraemon" was released in 1970 and the comics were serialized for 26 years. In the plot, Doraemon took out more than 1,300 mysterious props from his pocket. The time machine, bamboo dragonfly, and any door... are the childhood dreams of countless children.

Half a century ago, the author's rich imagination made Doraemon the originator of science fiction comedy comics, but it is precisely because half a century has passed that some of these more than 1,300 props have been realized unknowingly.

Time Machine Among Doraemon's props, the time machine is undoubtedly the most sci-fi one . This magical machine can lead us through time and space, back to the past or the future. Through the time machine, Nobita and Doraemon not only met their deceased relatives and witnessed the changes in history, but also had full expectations and imagination for the future.

With the increasing development of AI technology, it is not difficult to use AI to "resurrect" the deceased and reproduce their voices, appearances and smiles.

Previously, the People's Daily released a short video titled "Misplaced Time and Space" to commemorate the 100th anniversary of the founding of the Party. In the short video, restored images of 10 martyrs appeared. The most exciting thing was not just the restoration of the images, but more importantly, their faces moved.

During the production process, technicians used a series of artificial intelligence technologies combined with hand-painting to restore the blurred faces in old photos and colorize the old photos of martyrs. However, since old photos are relatively blurry, many processes are required during restoration. First, the AI ​​project "GPEN" is used to turn the blurred faces into high-definition and color, and then some hand-painted refinements are made based on historical materials, and finally AI is used to restore the skin texture.

When seeing old black-and-white photos of martyrs, many people may think that they are historical figures far away from themselves. However, after being restored by AI, their smiling faces make us feel that these revolutionary martyrs are alive and no longer just cold names in textbooks. Isn't this a different kind of time travel?

Bamboo Dragonfly

The bamboo dragonfly is one of the classic props in Doraemon . Whenever Nobita and his friends wear the bamboo dragonfly, they can fly into the sky and soar into the sky.

Today, as one of the hot spots for developing new productivity, the low-altitude economy , along with commercial aerospace, biomanufacturing, and life sciences, has been included in the government work report for the first time and has attracted much attention. The current center of the low-altitude economy is a new concept of transportation called electric Vertical Take-off and Landing (eVTOL), which has a less accurate but more understandable name - flying car . Although the name is "flying car", most eVTOLs do not look like cars, so it may be more accurate to call them "electric helicopters".

Entering the 21st century, with the technological progress in the field of batteries and electric distributed propulsion, a new thing called eVTOL, which can hover like a helicopter, take off and land vertically, and does not require an airport, has made its debut. Since electric motors are much smaller, cheaper, and more responsive than internal combustion engines, multiple engines and propellers can be installed on an aircraft to achieve distributed power.

Perhaps, in the near future, the science fiction vision of being able to take a flying taxi with just a few clicks on a mobile phone will shine into our real life.

Anywhere Door

A pink door. Every time you open it, you can instantly reach any place you want to go and start a new journey.

So, in reality, is there such a door?

I believe most people are familiar with high-speed rail. With the continuous advancement of high-speed rail technology, the time required for travel is getting shorter and shorter, and more and more stations can be reached. Whenever the high-speed rail arrives at the station and the door of the high-speed rail opens, we have arrived at where we want to go and can start a new journey.

Previously, the topic "It only takes 2.5 hours from Shanghai to Beijing" topped the Weibo hot search list. The Beijing-Shanghai High-Speed ​​Railway runs from Beijing South Station to Shanghai Hongqiao Station, with a total length of 1,318 kilometers. The current Fuxing train has a maximum speed of 350 kilometers per hour . If it can achieve commercial operation at a speed of 400 kilometers per hour, the travel time between the two places is expected to be shortened to less than 4 hours. However, with the high-speed rail technology currently under development, it is not yet possible to achieve a 2.5-hour high-speed rail journey between Beijing and Shanghai.

At the beginning of this year, the G852 Fuxing smart EMU train departed from Wuhan Station and arrived at the final station, Xining Station, in 9 hours and 5 minutes. This is the first direct Fuxing smart EMU train from central China to the Qinghai-Tibet Plateau, and it is also the first time that the Fuxing smart EMU has been on the Qinghai-Tibet Plateau . When the door opens, you can fully experience the infinite scenery of the Qinghai-Tibet Plateau.

Every opening and closing of the high-speed rail door will lead us on the journey to our destination. The high-speed rail has created China's speed and brought China's "anywhere door".

In addition, other props in Doraemon have also been realized. For example, isn’t the delivery phone the current online shopping + express delivery ? The indoor travel machine may be holographic photography technology , and AR and VR can also achieve the same effect; the badge that shows whereabouts is like a mobile phone, and it has long been integrated into our lives. Through the Beidou satellite navigation system , we can locate our mobile phones and know our location. This is a banner of China's independently built and independently operated engineering and technical projects !

Science and technology are changing with each passing day. Many high-tech props that only exist in comics and animations have been gradually realized and integrated into our lives. The author's happy and pure fantasy is based on a single scene. In the real world, technological inventions are more about solving problems in multiple scenarios. With the continuous development of new quality productivity , I believe that more and more high-tech props will be realized, and we will have a romantic reunion with childhood.
