This guy knows everything from cad to unity, mechanical to electrical to software.

a whole team of google engineers in the Netherlands are working on self-driving bike, this guy did it by himself only. Very impressive

This is insane. You did an entire team's work on your own and the result looks as polished as if it were done for a well funded commercial startup - except yours actually works.

I have a PhD degree. I have to admit this guy is better than 10 PHDs combined together.

我不得不說裡面結合多個領域知識，每個都是一個大坑，而能將其串接，並把模擬環境的驗證移到真實環境上又絕對是一個大考驗，太厲害了

Well done! That's an awesome way to deal with the bicycle balance, especially considering that even humans can't really balance a bicycle indefinitely once they've come to a stop. Kudos.

--0:55 Now we have the idea, let's look at what steps are needed to achieve the goal. The foremost thing is to make the bicycle go. Unlike a 4-wheeled car, a bicycle lacks a power source. Uncontrolled, it cannot stand up by itself, let alone getting it moving. Hence a complex control system will be needed. More on that later. Next, in order to take the rider (human) out of the picture, we need to supply a sensor network and a computer with enough computation power. This will be the "brain". Lastly, we need a sensory and control algorithm, this will be the "soul". -- 1:30 OK, let's look at step 1. Let the bicycle move.The bicycle I use is an old fixie (single-speed, brake by backpaddling) I bought earlier. Many foreigners like to use fixies for drifting, a danegeous endeavor. Fits perfectly with its Chinese name, death-fly (death: fixed, fly: the rear sprocket - which is ratchet typically). Did this contribute to the low population numbers of many of those countries?:)Back to business. We need to make some structure modifications to the bike. Similar to iron building robots, we use the computer to assist. Basically, building a model in a CAD tool. After messing with that, we got a virtual bike, or a digital twin. Essentially, draw up some wire frames, then add a few details here and there. All the modifications can now be done on the computer to get the final blueprint. In short, I added two humongous brushless motors, a servo for the handle bar. For sensors, I used a RGBD camera, an accelerometer, a gyro and a laser radar. The battery is type 6S for models. It’ll last 2 to 3 hours. The main control module is mounted behind the seat. For the drive train, the servo is obvious. But what do the brushless motors do? Let’s think about how a bike stands up when you ride it. Then how to achieve that when the bike is standing still. - 03:00 The answer is: angular momentum. From college physics, when one object in a system has a changing angular momentum, a torque will be applied on other objects. So, the motor in the center drives a metal flywheel. We’ll see its effect later. In fact, this is how satellites adjust its position in space where no friction exists. The rear motor is used to drive the rear wheel and the bike forward/backward. OK, the drawings are done. The next step is manufacturing the parts. Some of which can be 3D-printed. However, this time we are making something carry some level of power, the material for 3D-printing is not suitable for the core structure parts. These hardware for mounting motors, I used metal. I’ve got to thank my friend Xikii who likes designing and whose family owns a factory. All in all, after I used up an entire roll of 3D-print material and my friend worked at the lathe for a few days, I’ve got all the parts needed.

本来以为是纸上谈兵，UP主只是画画草图，谈谈设计理念之类。后来看到要对实物动手了，想到的是各种花式翻车的镜头，以为UP主可能是做搞笑视频的。从看到你踢开脚撑，车子稳稳定在那里的那一刻一直到结束，我唯一的想法就是：哇哦草。。。哇哦草草。。。哇哦草哇哦草草！

Very impressive! Kudos for this exceptional engineering achievement.

The addition of English annotations to the film will be greatly appreciated. Well done.

To be honest, this is the first time I see a project like this. This is insane and impressive

After playing scratch and lego robot for 3 days and learning ROS by myself, I can finally understand what you are saying! You are so excellent and we Chinese are all proud of you!

除了“臥槽！牛B”想不出別的詞了。牛頓被蘋果砸后發現了地心引力，UP主騎車摔了一跤后開發了智能單車。看來痛苦和挫折確實是人類進步的原動力，天將降大任于斯人必先修理他一頓。。。。

Wow, this is very impressive. It's amazing seeing someone do the same work as multiple videos from multiple engineering youtubers in one video, and it performs perfectly too?! You should have made this a series, people will expect too much from you now! Hahaha

太硬核了！这真的是让理科生重新燃起了对知识的激情！

Dude, this is incredible!

太強了! 真佩服這過程中的堅持及除錯的挫折忍耐能力阿

I think his best thing is time management. With such a young full-stack technology, he can complete everything by himself, record dozens of gigabytes of material, then edit and release, be interviewed, give speeches, participate in activities, and completion of these does not affect life and work. . This tycoon has a wide range of technical business and depth, system platforms, algorithms, various communications nfc wifi Bluetooth audio and video low-power server AI (tts asr image face, etc.), and then to various platforms (pc embedded android, etc.) ) And kinds of programming languages, all in one👍👍👍

one of the best IT channels on KZfaq ... keep it up dude

使用科技让人们生活的更好，你真是油管上最俊的仔啊！！

跪着看完！

The result is indeed uncanny and unnatural. Respect to you, that is half a lifetime of software and engineering work in one project.

我比你年長，但我真要叫你聲哥，不管你是否真的一個人完成，這project工作年足夠我幹一年了，而且從理論到實際效果非常好，真心佩服你每一個項目

Even though I didn't understand a word, this looks awesome! Keep up the great work!

Agradecido por tu esfuerzo en demostrar cómo funciona tu trabajo. Gracias por poner los subtitulos, se entiende mucho mejor. Increíble!!

My friend, my hat is off to you. You are what I aspired to be when I was younger. I look forward to your future accomplishments... and make sure you patent all your ideas to avoid being ripped off by corps.

You're an inspiaration to so many young students. We often loose motivation why we are learning science and math. After watching the video of your channel lot of young learners will be able to see the implication of science and math in detalis. Thanks for sharing your knowledge. You're a very good person.

"Tom Turbo" becomes real, now every bad guy should be afraid of. In my childhood Tom Turbo was a TV series with a autonomous bicycle with a lot of other tricks (I think 111). Tom Turbo was also detective and solved various criminal and mystery cases... thanks for this flashback memory ... btw, awesome work.

雖然領域不同，但身為一個工程師，我認為此人最值得敬佩的其實並不是技術力，而是強大到不可思議的執行力。

太強大了 一個人完成一整個RD team做的事...獻上我的膝蓋

Incredible stuff, you are amazing! 👍 Keep up the good work! 💪

Woh it's an amazing work! The future is now with you!

ビリビリ動画で色々なことにチャレンジする動画を見ていたけど、こういうできたら面白いで実際に作っちゃう人たちは楽しそうだし、ワクワクします。ひょっとしたらこの延長に素晴らしい世界が待っている気がする！

Applause and congratulations from Russia!!! Great job! I wish you the best in promoting this device!

Великолепно, товарищ! Я так восхищён вашей работой! Результат просто потрясающий! Есть чем вдохновиться!

不得不服！👍👍👍👍👍，以后老人的轮椅车要是用到智能这个技术，是全天下老人之福啊！

This is unreal, if this was in English I could see it having millions of views. Absolutely unreal I love your work

As a controls engineer, I totally admire your work 🙏

太好了，让我从头到尾看到一个自动驾驶的实现！！！

绝对硬核，惊叹个人实现技术迭代如此造诣，鬼斧神工，祝贺。

Tellement de compétences réunies dans ce projet, très impressionnant.

Great engineering work :) Lets face it, it has become time to learn Chineese.

好牛！～～～膜拜行业大牛，请继续加油！

I look at what you are doing, you can understand one of the factors that make Chinese technology grow so fast. You are genius engineer.

wow，James Gosling转推了

ME: While watching this: Oh.. this looks cool. Pokemon Emerald Littleroot Town music plays: OH THIS IS GREAT!

Really amazing!! Appreciate your efforts.

谢谢您的无私分享 感恩有你们的才干。

Great idea 💡! Greetings from Germany 🇩🇪! 😉

Amazing work!! bring this thing to Canada it would be very popular on the bike trails

哈哈，占个前排，观赏大神表演！

偶像🤭 讓我對我未來進修的方向有更多明確性了 希望能向up主看齊

YES! English subtitles or an English version would be lovely!! You have such creativity and brilliance combined!!! Thanks from Canada!!

彻彻底底的解释了 知识就是力量的都市传说

This is rad. Great project!

This is a game changer. I hope you have all the Intellectual Properties applied. You might become the next DJI because it has a huge market space.

If you change the reaction wheel to be an open design and like fan paddles, you can use air friction so that it won't go to 1000000RPMs when the bike is imbalanced!

Congratulations from Germany on this extraordinary achievement, I am really impressed and wish you all the best for the future

Congrats from Switzerland. Well done.

Kudos to you. Very impressive. Great Job

Amazing design, brilliant in its simplicity, admittedly not useful, but it shows how little we need for intelligent devices. You can compete with Tesla. Bravo you! Congratulations from Poland

德国祝贺这一非凡的成就，我真的很感动，并祝你们未来一切顺利

Great! Now lets try to fit all that tech inside those frame tubes and we are on business!

Amazing work! Greatings from Poland

看完视频我决定去好好读书。妈呀大佬牛逼

Congratulations from Spain, I am really amazed by your ideas and the way you get them real, I wish you the best! You are a genius.

加油，野生钢铁侠，期待你更好的作品

I don't understand anything, but the results are impressive. Very nice work ! Congrats :o

这不是华为的天才少年吗？ He is one of Huawei staff recruited under talented youth program. Look at the Chinese proprietary 3D CAD tool. Its amazing. Two wheeler is much more difficult than 4 wheels for autonomous driving. And he is releasing his design as open source for free download.

20年後看到影片的人: 原來自行車不是因為自動駕駛才叫自行車?!

太贊了，由衷的讚嘆

太棒了！很厉害！加油!

中国有你这样的人才怎么可能不复兴起来，加油，期待您更多让大家惊叹的作品。

What a coincidence. Earlier today, I watched a video on Google's KZfaq channel about self driving bicycles which was an April Fools joke.

Stunning. Great work.

中国需要一大批你这样的人，加油

能从理论到产品还是很利害的

太牛逼了，特来膜拜！

大神的視頻從來沒讓人失望

if this dosen't deserve a subscribtion, then nothing does. Amazing work! I'm so impressed!

超強，能夠從軟體到硬體獨立實現

大神太牛了！

you’re something different, keep at it and you’ll change the world

又一个好产品。赞。

Tu esfuerzo es inspiración. Felicidades y gracias por inspirarme... Yo, apenas iniciaré con Arduino Uno. Muchas gracias.

华夏文艺复兴的感觉，致敬小哥

老哥稳！技术很强！

我每個部份分開看都可以，組在一起就不行了。 鬼才

Não entendi nada, mas que espetáculo da engenharia, parabéns 👏👏👏

This is what I was wondering last year,and you made it really good….the giro scope it’s fantastic,the only thing is that I don’t think that it can last a lot with a little battery pack..

感謝分享！看得很感動

做得好，车子很漂亮

真是天才博士............感謝分享

死飞通常跟脸刹有着密切的联系的。

厲害👍！加油！

不是一般的厲害👍

超级全栈工程师，是的，他的开发技能甚至延伸到机械cnc，3d建模，cad，unity，以及物理模型构建。。。

Finally, this became real

A bicycle that steals itself! Astounding!!!

超级棒!!加油!
