good robot sir.. do i need to have motor with encoder in order to make smooth turn like your robot? or just by using line sensor array.. my robot with only line sensor cant make accurate turn like yours despite after trying many code combinations
My smooth turns are achieved by a high-density line sensor array and high-gain PD control. I use original line sensor array and the pitch of photo diode is 7.5mm. The sensor array has 16 photo diodes.
hey man, nice robot. Are you using the pololu's sensor? What is the sensor brand? And about your robot, in the first lap, do you do a maping of the track to run faster in the sencond?
Thanks your comments. I don't use pololu's sensor board. I use a IMU board which is able to buy in Japan. And I use original sensor array board which is mounted on IR LEDs and photo transisters to observe the position of the white line. I introduce a detail of the board in another movie. By the way, the purpose of the first run is exactly what you commented.
Hey can you share the code you use? It speeds up in straght line and down in curve . Like how the algorithm is managed to do that. Or can you give any source where I can learn the coding algorithm? I will be very gratefull if you do so?
First, the robot car learns the curvature of the course in the first run. Then, in the second and subsequent runs, the robot car travels at a speed that is something like the reciprocal of the memorized curvature. The curvature can be detected by the gyro sensor.
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.

Which size brushless motors did u use ?
and ı want to now how to callibration works, how did you write the code for callibration?
Amazing look

Pololu is sh*t, try maxon or faulhaber
Nice one bro. How can you memorize the track? and what library do you use to code?. I am so grateful for your help.
The robot car estimates its own position and learns by its trajectory.
are the propellers to maintain downward force so that the car doesnt flip over when going extremely fast?
Not only that, but it also enhances the grip of the tires.
Nice one sir. What motor do you use? Thanks in advance and God bless
I use Maxon's motor. Thanks.

Correct me if I'm wrong, but, are you using the inertial force of those motors to do a Z axis correction when your robot turns?
In the Z-axis direction, the robot is generating a force to push against the floor.
@@ShachikuHakase I thought you were using those motors varying the speed like a drone does to rotate on Z axis. That could be a nice thing to see.
Sorry, What is the product name of your flight controller board.
Sorry I forgot it. The BLDCs driver module is 20mm x 20mm but the name is....... :-(

Which motor you used and how much rpm, voltage??
Would you please give the list of materials you’ve used?

Пропеллеры нужны для увелечения прижимной силы?
Yes.
Nice..
Thanks.
ı am makinf line following robot too and see a lot of japaness people putting fans at their robot, why is that? is it like a cult thing?
Because we want to get more downforce.
私もそのような製品が欲しいのですが、どこで買えますか? それとも誰かが私を導くことができますか?

Nc!
why u dont use EDF in Japan? Ducted fans provide better downforce actually.
