タイム
1周目 17.47s
2周目 6.47s
3周目 6.47s
コース継ぎ目の凸凹が激しく、まともに走れているのは奇跡。
右奥にツボと大明神がいるのが非常にツボる。
1/10s以下がすべて同じ数字という奇跡の1ビデオ
海外の方がたくさん見てくださっており、ありがとうございます！
イントロダクションでしゃべっていることを書いておきます。残念ながら私は英語が苦手なので、日本語で書いておきます。
「
個人参加、Fujisawa Akihiroです。ロボットの紹介をします。構造は、変則4輪 [1]に、ファンモータが4つ[2] 搭載されたオーソドックスな構造をしています[3]。最大の特徴はラインセンサで、ユニバーサル基板とプリント基板をハイブリットに使っています。これにより、ラインセンサの安さと大きさを両立しました[4]。裏面は、黒いフォトトランジスタが16個配置されています[5].それでは、走行動画をご覧ください。

[1] 変則4輪：マイクロマウスにてよく使われるホイール配置のこと。スキッドステアというらしい。
[2]ファンモータが4つ：ドローンをひっくり返してとりつけるような感じである。ダウンフォースを大きくするために4つつけているが、重量が重くなる欠点がある。
[3] オーソドックスであることは、冗談である。（確認していないため）
[4] プリント基板で 100mmを超えるサイズを作ろうとするとコストが高くなる。そこで大きい部分だけユニバーサル基板で作ることで、コストを低減した。ラインセンサの長さは100mmを超える。
[5] MCP3008 AD変換IC 2機の最大の接続可能数。16個なくてもライントレースはできる。
Great little car and great creator who takes time to answer so many questions 👍🏻 This is simple compared to self driving cars, at the same time we can see what machines can do that would be impossible for humans! Keep up the good work 👍🏻
This is very impressive! Heelo from South Africa!
Hello dear,
My name is Alexander and I live in Brazil.
I saw your video many times trying to understand how its possible! How to be so fast ?
Congratulations !!! Very good !!
Very Nice project. Well done !!
Alexander, só de olhar da pra perceber que além de aderência nas rodas ele colocou controle PID no código!
A cada volta o robô armazena na memória e vai melhorando com o controle PID deixando mais rápido!
Controle PID é sensacional!

Olá Lucas,
Adoro esses brinquedinhos...
Sou tec. Em eletrônica, mas não entendo de programação.
Vou pesquisar sobre PID que comentou..👍
Thanks your comments. As you say, I programmed a PID controller for rotation. Moreover I programmed a 2DOF controller for speed control. And for fast running, the robot has high-grip tires, light weight body and downforce system.
I am a fan of your work, what you have achieved is incredible my friend, greetings from far away from Chile
Greetings from Poland, Europe!!!
@@8starsAND Greetings from Czech
@@8starsAND And btw awesome tournament w Rybniku
Очень интересно, молодец!
Exactly the same time, very efficient.
Hola amigo, escribo desde Colombia, excelente demostración. Muchas Gracias
Thanks.
duude awsome i would love to build something like that...
I’m cheering for your trying!
Tesla want to use a system like this, is it already done ?
Great work, it's incredibly efficient !👍👏
That’s nice of you to say.
@@ShachikuHakase
Can you please tell me
What some bot used as a third support at front and back
If Robot is two wheels robot
I saw something like double sided tape
On pololu 3 pi They used free wheel caster wheel
In micromouse wall maze robom they used brown colour tape something
What is that material
Please share any buy link so I can get idea of what materials used
Magnetic track:)
Good....F1's Down Force!
Awesome movement. Could i have this robot and ship to indonesia? I'm very interesting research on speed line follower. Very interesting to know your robot performance 👍
Thank you but... I won't give anyone the robot because the robot is the only one. Please enjoy this video!
@@ShachikuHakase
Which software used for coading smt
Fantastic. Are the fans for cooling or to increase grip on the track?
Thank you. Those fans increase a grip of tires. The purple fan on a black brushless motor generate downforce.
@@ShachikuHakase thank you very much for your answer. Congratulations it is truly an incredible project
@@ShachikuHakase
Do you run those fan on full speed
Or speed is dependent on track , turns
@@Shubham-po2tp Fan speed is dependent on turns.
@@ShachikuHakase
Thank you
Do we have to slow down those on turns and fast on straight track
Please tell me something
what it takes for a high grip tire Thank you. very nice vehicle
I use 20mm diameter radio-controlled car wheels and original design tires. The tires are made of 2mm thick EVA sponge and high friction silicone sheet. It is easy to obtain it in Japan. Thank you for your comment.
Would you please give me the link of wheel you used??
@@ShachikuHakase im doing RC racing for years & we use a special spray on the tires to get more grip(not all leagues allow it tho)... is that a thing in these "races" too? or illegal?
why is the next run faster than the previous one, can you tell me what algorithm you use, tks very much
In the first run, the car records the shape of course. After the second run, it accelerates and decelerates based on the record from the first lap. To do this alrorithm, the car has gyro sensor and rotary encorders.
lmao I wasn't ready for the second run
Hello, what type of tryes use what reference? And why do you use gyroscope? Amazing
I use gyroscope to map the curvature of the line. In the first run, the robot runs constant speed so the gyro sensor time series data is proportional to the curvature. On all runs, the robot is controlled to follow the line, using the deviation from the center of the line as a reference.
Thank you so much, another question jejeje what reference is the motor driver, what reference recommend for this, i wanna work with BTS7960😁
Do you use LQR and stuff like that?
I use PD control to follow the line and 2-DOF( = I-PD and FF) control to control the speed.
can you explain what's the function of this white small lines
The small lines on the right side of the line are for start and goal recognition.
The small lines on the left side of the line indicate that the curvature of the line changes.
there are stores that sell such plates
I need EN subtitles
Which microcontroller used
STM32F103, I used.
@@ShachikuHakase
Thank you....
Which sensor used
@@Shubham-po2tp I used 16 general phototransistors , 2 rotary encoders and a gyro sensor.
@@ShachikuHakase
Thank you.......
Please tell me tire grip
I saw some people use silicon in jsumo
But they are costly
Where to find such tire wheel
Shubham 99, thank you for your interest and many comments. I read all of them but I can't respond all, because I’m using all of my free time to update my robot.
I can't say all of my technology because I'm going to use it in the next robot competition.
Moreover, I have researched it for 10 years, so it's difficult for me to teach my technic simply.
If you want to make a robot like that, I recommend ...
1.You should study and use high gain PD control for line following and 2DOF control for speed. You also should build your robot to be able to use them.
2.You should use high grip tire like silicon seat. You'll get high speed turn. (Of course, I use it). It’s easy to get the seat in Japan, but I don’t know how to get it overseas. Please devise it by yourself.
I wrote what I said in introduction on the description. Please translate it to your language.
(Please use all of the information from me at your own risk).
Can you guide me to do it?
Someday..I'll guide about it..
If the day has come, please guide now🥺
I will make one, would you be interested in advice and sharing? Not like you, I make a lot and this project is simple, I can help you improve your product, It won't be secret. My solution might not be pretty good in your case but whatever, when I make it, I will find your newest video and ask for contact. I'm in the way trying to share "stuff" with people like me around the world. Sorry, My English is so Bruh Bruh Bruh.
how can you get the board or the circuit as it is made?
