Dancing robots were the stars of the night at the CCTV Spring Festival Gala this year. Singer Sun Nan performed with a total of 540 robots at the Guangzhou Gala venue. Read about the background of the act and meet China’s first humanoid robot Alpha 1S.

The Alpha 1S became famous overnight after its impressive performance at the CCTV Gala. It was a case of “ten years of practice for one minute on stage” (“台上一分钟，台下十年功”), says the Tech reporter at China’s news platform Tencent. They spoke with the technical staff behind the robots after the Gala. Chinese Mandopop singer Sun Nan (孙楠) sang the song “Going to the Top” (冲向巅峰) as 540 robots were dancing around him, all doing exact same movements at the exact same time.

Meet Alpha

The robot is China’s first humanoid smart robot. It belongs to the Alpha robot family (阿尔法家族) and carries the name Alpha 1S. It is a truly made-in-China product, developed by Chinese tech experts and locally produced. The creators of Alpha 1S, Chinese company UBTech (圳市优必选科技有限公司) spent five years and over 50 million RMB (7.6 million US$) to produce their star robot, designed for families. In many respects, Alpha 1S is a pioneering work, especially when it comes to the patented computer system at its core. According to Tencent, its technique “surpasses that of American, European, Japanese and Korean robots.”

One of the reasons why Alpha has such good dancing skills is because it has 16 different joints, giving the robot the freedom to move like a human.

His eyes are flickering blue-ray LEDs with sensors. On the evening of the Gala performance, all robots were numbered so that technical staff could control the twinkling of the eyes in every single robot.

The robot’s software is compatible with both Android and IOS mobile systems, and can also be linked to a computer. Users can edit the robot’s programme themselves, which is also possible for people with little knowledge of robots or programming. Even more awesome: you can preview the robot’s movements in a 3D visualisation on the computer, making it easy to edit and change its movements after seeing them on screen. With the Alpha app, it is also possible for owners to programme movements by playing around with their robot; it will then remember the movement sequence. This means you can let the robot dance in whatever way you want (- we cannot get over how cool this is).

The Gala performance

On the night of the Spring Gala, a total of 540 Alpha robots were lined up in a military square-shaped formation, standing in four groups of 9 x 15 robots. The technical staff had programmed the robots with 12 sets of dance steps, all of its movements in line with the rhythm of Sun Nan’s “Going to the Top” and completely in-sync – a Guinness Record.

According to Tencent, Alpha 1S was only invited to take part in the Spring Gala one month before Chinese New Year, letting the technical staff, a team of 36 experts, work day and night for an impeccable Gala performance.

In order for the performance to go smoothly, the staff also had to deal with two problems. The first was that the robot originally could only have a maximum distance of 50 meter to the control desk. This distance needed to be bigger for the great Gala venue, for which experts changed the transmitter, making it possible to control the 540 robots within a range of 5000 meter.

Another risk was that colliding robots would result in a possibly disastrous domino effect. But for the camera to properly capture the perfect formation of robots, they still had to be lined up near to each other. The LED lights in the robot’s eyes with sensor were thus programmed to be ultrasensitive to distance and to stay within a 0.6 m x 0.6 m distance.

Every millisecond of the performance was tested in great detail and practised over and over again to make sure nothing could go wrong on Sunday night, February 6th, during the live show of the Gala.

China’s future

Alpha 1S is China’s first programmable, interactive and affordable robot meant for family entertainment. The features of Alpha 1S are promising and show that much more will be possible in the near future. Alpha’s brother Alpha 2 will be less affordable (around 8000 US$), but can already do much more than dancing; this robot can act as a tutor, translation, personal assistant and help doing household tasks.

Weibo netizens praised the robots’ Gala performance. One Weibo netizen says that her boss bought the CCTV Gala robot, and that all people in the office put their work down to see the robot dance along to ‘Gangnam Style’.

The Alpha 1S can be bought online. On Taobao, the robot is sold for around 3000 RMB (±450 US$)

On a side note: remarkably, the multiple promotion campaigns for the made-in-China robot does not feature Chinese-looking models – making it seem like an American or European product.

A woman named Sima comments on Weibo: “What interested most about the CCTV Gala were the robots dancing together with the drones on Sun Nan’s song. It was such a novelty – this is China’s future!”

TikTok’s In-Video Search Function (And How to Activate It)

TikTok shows a glimpse of what in-video search is going to look like in the future.

What is TikTok’s new in-video search function and how to activate it?

Twitter’s most awesome WeChat guru Matthew Brennan recently posted about an “in-video search function” launched in the Chinese social video app TikTok (抖音). (Click here to read about the difference between the Chinese and overseas version of TikTok).

As shown in a video posted by Brennan, the function allows TikTok users to select the face or clothes of a person appearing in a short video to search for other videos or images containing the same person or clothes.

The ‘vision search’ is a powerful new function within the super popular app.

The idea is that it becomes easier than ever for Tiktok users to find (and buy!) a piece of clothing, that perfect handbag, or even a snack featured in a video.

It also helps users to quickly find other videos in which an online celebrity appears. The function ultimately is an additional feature that keeps users scrolling and shopping within the app – increasing app traffic – as long as possible.

On September 16, Chinese media reported about the function as a “powerful” new tool that greatly strengthens the functionality of the popular short video app.

The function might not immediately seem completely new to Chinese app users; like Google Image Search, Baidu and Taobao also have similar functions (百度识图, 淘宝识图).

On e-commerce platform Taobao, for example, you can take a photo of an item you want (e.g. a certain snack as in example below) and Taobao will try to find the exact same product and list the online stores where you can buy it.

But TikTok’s in-video search function is on a whole new level; it does not require users to scan or upload a photo at all. It gives an indication of what visual search will be like in the future.

Whatever video comes by in your TikTok stream, you only need to click the “search” function (识图), select the part of the video you want to search for (you can drag the square from area to area), and TikTok will find the product or face you’re looking for – as long as there are comparable products/faces (it does so very fast).

Very much like Taobao, TikTok will recommend various (in-app) online stores where the product can be purchased.

Want to try out the function? For now, it only works in the Chinese version of the app and is still in the ‘testing phase’ and does not work with all videos.

Make sure you have an updated version of TikTok.

1. Go to “me” (我) page within TikTok
2. Tick the three lines in the top right corner
3. Go to the last option in the sidebar menu titled “lab” (实验室)
4. Activate the function (image below).

So now if you spot a dress you like and would like to buy, press the ‘search’ button on the right of a video, select the dress, and TikTok becomes like your personal shopping assistant looking for similar dresses for you.

Tiktok makes shopping supereasy.

This really makes online shopping more addictive than ever, and also makes it more difficult for people in online videos to hide where they bought their clothing, or what other videos they are in.

Didi Riders Can Now Have “Verified Party Members” Drive Them Around

Party-building 3.0? Didi has got it covered.

This is Party-building in the new era: Didi now allows users of its Premier Car Service to let a verified Party member drive them to their destination.

On September 20, as the People’s Republic of China is nearing its 70th-anniversary celebrations, the country’s most popular taxi-hailing app Didi published an article on Weibo and WeChat explaining its verified Party Member Driver Program.

Recently, riders in Beijing may have noticed something different at Didi’s Premier Car service, which is called “Licheng” 礼橙专车 since June of last year.

Some of Licheng’s drivers now have a red background to their profile photos accompanied by a Communist Party emblem. Upon clicking the profile of these drivers, customers will see that this driver is a Party Member Driver (“党员司机”) – meaning that the Didi driver’s status as a Party member has been verified through Didi’s “Red Flag Steering Wheel” program (红旗方向盘项目) that was set up in November 2018.

Didi writes that these drivers can also be identified as Party members through the red sticker on the dashboard at the passenger side, which literally says “Party member driver.”

The article explains that the recent project is an effort to contribute to China’s Party-building in the digital era, and that Didi aims to establish a Party member community within its company.

The company is apparently planning to make this community a lively one, as it promises to provide online and offline activities that will help these drivers stay up to date with the latest developments within the Party, and that will increase their “Party awareness.”

Starting this month, Didi will reportedly also offer “patriotic classes” to all of its drivers via its online classroom program.

China has more than 88 million Party members. Party membership does not come overnight; those who want to become a Communist Party member need to attend Party courses, pass written tests, be recommended by other members, and pass a screening (read more here).

As for now, riders cannot manually pick to have a Party member as their driver; a nearby driver will be automatically selected when they order a car – if it is a Party member, they will know straight away from the driver’s profile.

For now, Didi has set up “mobile Party branches” in Beijing, Shanghai, Shenzhen, and a number of other cities.

On Weibo, some see the initiative as a marketing move from Didi’s side. “If you hear the driver is a Party member, you know it’s reliable. It’s a good thing.”

The past year was a tough year for Didi, after the murders of two young women by their Didi driver made national headlines, causing outrage and concerns about customer’s safety when hailing a car through the Didi company.
