Thank you for this very important video I would greatly appreciate your help in converting this code to the newer picamera2 library. I am new to python and haven't been able to figure it out, Thank you

Use medium motor

Good job😃

Excellent!

Hello, thank you very much for such a good explanation. I have a question, I placed the 2 motors backwards, i.e. the shaft is at the back and the motor in front. In this case how would be the direction of rotation for the 3 cases?. I tried to change the speed to negative (-30), but it did not work, the robot started to go out of the line. Could you please help me?

hi admin, what do you use to give the raspbery pi the power needed, is it powerbank ?

How did you do to download openCV on the pi?? I'm trying to download it but unfortunately I can't

Great video. Thanks a million. I'll give that a go.

can you share the program code?

holy cow

Is there a contact I can contact other than in this comments menu, I want to ask a few things

sir can i please have your email

(xBox, yBox) = box[3] cv2.circle(image, (int(xBox), int(yBox)), 10, (255, 0, 255), 3) (xBox, yBox) = box[0] cv2.circle(image, (int(xBox), int(yBox)), 10, (0, 0, 255), 3) for opencv recently the first corner is index 3 and the second is index 0

Dude this tutorial series is amazing! I can't believe you don't have at least 30k views or so! A hidden gem on KZbin!

Love your accent mate! 😂 Good video. Thank you.

Hi, Is it possible to make this work on a Motor which is ripped off from a PSP UMD Drive using any Microcontroller? There are 4 Pins. Can someone help me with the Pin Connections?

The greatest line following Teaching videos I've ever watched!! Sincere thanks!!

Hello

Hello

Thanks!

you miswrote binary

Onlyif the robot could move faster...

a question...i use this device on an arduino...does reading CNTR register influences the counting?Because on the data sheet productor writes (i understand this manner) to read back from OTR register...what is the right way ...?thank you

It will be slow i will like to use logic gates and D Flip flop to get quadrature pluses and direction signal.

Can u do a tutorial for the robot

not working

very nice...

Excellent! I was trying to figure out why you would want use the counter chip prior to buying everything for a project. Thanks!

Nice

I use your code，but the FPS just only 26，and your video final FPS is 50，I wondering if my power supply is not well(I use power bank 5V 2A ), is it?Thanks for your answer!

Hi，thanks your video，I have one question: When detect more than one black line，we need to find the correct line, but when it just only one line and the error takes place: (y_ highest, con_ highest )=canditates [contours_ len-1] IndexError: list index out of range . How to solve it?

Great Job!

Superb

hello and thanks for sharing this! I wanted to do similar project and i wanted to know what hardware did you use for the robot?

Hello Out of the BOTS. I'm going to do counter reading on stm32 using ls7366r, but I couldn't do it anyway. Can you help me ?

Thanks for sharing. But did you try to disable wifi first? Did you use interrupts as well?

awesome videos. kindly what level openvc tutorials I should learn to be confortable using opencv and understand the functions you are using in your code.

nice, i want program follower 4 sensor

good ,i want this program with 4 sensors

Thank you so much for the amazing presentation and the code! It helped me a lot with my encoder!

Thanks, exactly what I wanted to know, short, sweet and easy to understand

best explaination

very interesting tutorial

I am in the leggo league 💪😎

Brilliant video and explanation. As others have noted, the outcome needs to be changed to match the table... Then it works flawlessly: outcome=[0,1,-1,0,-1,0,0,1,1,0,0,-1,0,-1,1,0]

arduino or raspberry?? esta genial. Saludos desde Argentina.

Really nice. It should have been a hard work. Congratulations !

Hi there! I’m a primary teacher and we’ve been following your videos for learning ev3 robotics. We’re really struggling with this one, we’ve managed to get it to turn right on a green square intersection but even though we’ve copied and changed the inputs to the correct sensors it won’t do it for turning left. Any help appreciated. We use the ev3G language.
