U are younger then me , but u are better then me U did a very great job of creating this genius programme

Thanks so much for sharing, I had the team I was coaching watch this video. You did such a good job of explaining that the 5th graders were able to program themselves and even troubleshoot per our unique lighting challenges. You deserve a hug.

Thanks for the tutorial. My 8 year old daughter was able to input the program and we got it working with a little trouble shooting... we had the Move Tank set to On for Rotations rather than just ON. So great to finally create something with the EV3 that works really well. We created a wavy line and it still followed it smoothly at 50% output to the motors. Thank you for your video!

I'm impressed by the way you handle the theme, you make it awesome, keep that way and you'll go far

Amazing video! Wow, you are one talented and creative kid! Thanks SOOOO much!

Thank you for a wonderful explanation. Great idea on having the 'C' variable in the equation.

Thank you! This was a great tutorial to follow!!!! By far the best I found on this task :) Thanks so much!!!

Hi Emma, You are an inspiration for my students. This was very helpful for us.

Very nice job. Clear instructions and good explanations. Thanks

Thank you, Emma! This really helps! It is really complicated.

great video👍 the program worked really well

Great job! The program worked perfectly.

how to follow a line smoothly AND do left and right curves

Woooww the best video "following a line" I have ever seen on youtube..

Thank you very much, this tutorial was very helpful! You give very good and clear instructions.~Em

this is really helpful nice and clear instructions... keep it up >.

LOVE this video. Thank you so much!

You did a very good job, Emma. I love blue angel robotics.

Wonderfully done! Thank you!

Very very much useful THANK you VERY MUCH

Thank you for the tutorial very clear instructions

This is very nice, I loved it, good luck Blue Angel :)

Thank you, Emma! You are good!

You guys are so good at robotics!

how do I test for a quarter? That would be great.

Hi! Would this work if I needed the robot to follow a white line? Also, do you know a good program for following a white line up a board that is inclined 30 inches?

working smoothly! Thanks!

It's so helpful! thanks!

thanks a lot my friend you saved me

You did a great job!

Thanks this help a lot!!!

Thank you for sharing your time & expertise - very cool & easy to follow. What are the implications of putting the read variables on a second line to feed into motor power, vs. just appending them to the end of your original path? I didn't realize seperate paths could just dead end (like after feeding the motor) - thanks for that tip too!

Thanks, it was very helpful.

wow hank, that was really helpful :)

I suggest you get a better mic, at least a decent one, there was a lot of this, cukkkkkk in your mic. And thanks, this will help me out in my Robotics class, after a summer I forgot how to. I competed in my country's Robotic Olympics, but idk why. Ey Blue Angel, did you compete in the WRO?

I have a problem now, I changed the C value once then changed it back but now the B-motor keeps turning in sync to the C-motor on right turns and I am very confused. Could you please tell me if there's perhaps something wrong with the program or anything else? Thanks!

Good work!

This is great, I will subscribe this.

my robotdid not follow the line and it only moved if it was on the white but if it went on the black it would not move at all. plz hlp

This is a great explanation on how to use Data Blocks in an EV3 Line Follower program. I like how you show the math involved, and how you superimpose the robot's turning action onto the EV3 program screen -- it really helps understand what the B-Motor and C-Motor are doing. Our FLL team has been using a simple switch-within-a-loop Line Follower program, but the robot "waddles" too much and the driving action is not very smooth like your program is. Keep posting these kinds of videos -- they are really helpful!

Excellent video. :)

can you please post a video on the bot finding the lego remote.

your programming is superb....hope that you can post more...i learn more with u...hehehe:)

:) Great video keep it up.

your smart you know and thanks that helped me a lot with the math blocks

Hi the robot can catch the line from the right edge of the line but what i want is i want my robot to catch the line from both side how can i do it thanks.

Can anybody tell me how can ev3 detect randomly placed object in an arena and how ev3 will distinguish between fence and object? Beacon control is not allowed.

after troubleshooting my ev3 i found that the port on my color sensor block did not match the port i connected it to

I take it back works perfectly thank you

Thank you for the tutorial. Does it work on sharp turns too?

GOOD JOB!

Is there a way to make the robot a bit faster?

Hi, Thanks for sharing the beautiful program. I tried this one at home but once it exits the black line and white comes it starts spinning. This happens only during a left turn as it turns right when it sees white. Can you please guide me with this?

Hi blue angle u did a great job may i ask u question i do same programming but the problem is so slowly the robot how can robot be fast with ur program

Hi Emma! Is it possible to make the robot stop after it sees no black line I need this for a project. Or is it possible to make the robot stop when it sees no ground (exe) i put it on a table and it goes straight to the edge and stops?

Hi! how can I make this faster? because if I put a bigger value (like 1) the robot is not/following the line straightly.

Great video!!!!!

Yes thanx i crease the c its work 😍but i have another question 🙈if u dont mind iwant to put another sensor how can i complete programming at the same program that u did

Merci beaucoup pour cette video très simple mais très utile

hi, i have a problem, i folowed u`r instruction, got irl for black between 8 and 12 and for white between 62-72. so i`v made this program, but the robot isn`t folowing the line, hes turning to much and lose the line, then its start to spin in circles. what is the problem? do i need negative powers? the color sensor is situated between the wheels, exactly at the midle point where are the red parts of the motor

Hi I need help with a program which is very complicated! I want you guys to teach me how do reverse the robot onto a black line and keep on moving forward? Please reply to this message and please make a video about this 🙏

thanks for the video. it desnt work with me. whats the problem?

thanks for the videos

Please make an updated version, as when i did this my robot just spun in circles and didn't follow the line at all.

this doesn't work for me :c the robot just spin around the line plz help us!

I in a robotics class and as a test, my robot has to go through a maze.Can you help me?

this is a really helping. I built the robot and it seems to work very well in smooth curves but fails in sharp corners even if I reduce the speed. please help

Thank u

how many color sensors do you need for this im looking for one with two sensor

this program follows the left edge . what Changes should we do in order to follow the right edge?? plz help

It works thanks

Question. Any ideas on how to make it follow the line faster?

works great I subscribed but is there any way to make this program faster so the ev3 can move through the line in less time

Amazing thanks

You're very good

Hello, My robot forward is backward. So how can I change the values in this program?

Hi Emma! A big thank you from Belgium for your very usefull lessons! The kids in my classroom, P5, actually are learning to program the EV3 robot by watching your videos! We are very interested in your lessons for following the black line and recognizing the different colors. We are trying to combine the two ideas into our program for following a black line, then switch to the yellow line as a shortcut, and then switch back to the black line again. For My students It is a hard nut to crack... Could you help us? And a big thank you again for all the good work!

why u didint try the block coding to see whether it was working or not

10/10 would copy and paste again

Thanks

how many color sensors did you use in the robot?

What if i wanted to use 2 color sensors on each side of the EV3 in order to follow a "road?"

Can you make a vid where you are using one light sensor? I only have one and my robot was all over the place that would help a lot ;)

how did you get to the 78 and the 8 values

dude VERY COOL MAN.

You have more subs than my teacher

this is good

I need to download right.

hi :) my robot has to follow a red line what should I do ?

and which value "c" is needed to increase?

thanks شكرا

Are you from Singapore?

Thanks very job +1

I am using a different bot and it is too heavy. how to account for this?

how do you make it go faster and also make it stop at a white line if it is following a black line?

Errrr...I only have 1 colour sensor. Could you do a video with 1 colour sensor?

How could I use this for following a green line?

bravo

What do I change of my motors are A and B

HOW CAN I SPEED IT UP MY INTENSITY IS TOO MUCH LOW
