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 👍🏻

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 !!

[@LucasOliveira-xw5uy]

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!

@@LucasOliveira-xw5uy Olá Lucas, Adoro esses brinquedinhos... Sou tec. Em eletrônica, mas não entendo de programação. Vou pesquisar sobre PID que comentou..👍

[@ShachikuHakase]

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.

[@PauloHenrique-lb1xd]

Hi friend! Do you make this high-grip tires by yourself?

[@henryescobarmontoya8918]

Hola amigo, escribo desde Colombia, excelente demostración. Muchas Gracias

[@ShachikuHakase]

Thanks.

[@PiyasKheyal]

What kind of motor are you using?

[@penniesshillings]

This is very impressive! Heelo from South Africa!

[@flyerplanet]

Fantastic. Are the fans for cooling or to increase grip on the track?

[@ShachikuHakase]

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

I’m cheering for your trying!

[@gokhanaldemir9553]

what it takes for a high grip tire Thank you. very nice vehicle

[@ShachikuHakase]

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.

[@fahimeee3]

Would you please give me the link of wheel you used??

[@mho...]

@@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?

[@shubham9672]

​@@mho...Which spray

[@michaelalexandralopezyugch3436]

there are stores that sell such plates

[@Jawadayoub-gg1qx]

can you explain what's the function of this white small lines

[@ShachikuHakase]

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.

[@basketballhightlight2430]

why is the next run faster than the previous one, can you tell me what algorithm you use, tks very much

[@ShachikuHakase]

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.

[@gilangkencana250]

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 👍

[@ShachikuHakase]

Thank you but... I won't give anyone the robot because the robot is the only one. Please enjoy this video!

[@juancuellar4981]

Hello, what type of tryes use what reference? And why do you use gyroscope? Amazing

[@ShachikuHakase]

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.

[@juancuellar4981]

Thank you so much, another question jejeje what reference is the motor driver, what reference recommend for this, i wanna work with BTS7960😁

@@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

[@ShachikuHakase]

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).

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.
