Here is our first built robot ever! It is a line following robot, that we built in school. Please visit our site http://www.korforfan.se/ for more information

What do you think about it?

If you like to see more videos there are some @ http://www.korforfan.se/ or I can post the vidoes here, if you are intrested!

Nice..... the back wheel setup is cool!

When the robot it moved back and forth over the line before it is set loose, is that for calibration?

nice job

Thanks

We are three people that done this project. One programming, one building and the last one planing everything.

In Sweden everyone in third class at the gymnasium doing a project that scould take around 100 houres, this project is ours. And the one that planning everything also do the filming.

u used all readymade controllers?

and whih mcu??

we bought our things from http://www.hobbytronik.se. It isn't a kit! We bought part by part, and used some Meccano (it is almost like Lego) to build the bottom.

Dont really understand what you mean with whih mcu??

He wants to know what microcontroller you used.

@video What the F___ why did you record your friend mooning you.

@Robot That is a very nice robot, I like the back wheels, but it doesn't seem like it helps it that much.

Very nice work, I especially like your back wheel set up.

Thanks all for your compliments!

Here you have a video where we show the robot (its in Swedish)!

Hey I have been trying to get into the build of a line following robot but the only problem is. . . I dont know how! if anyone knows any good books or walk throughs, kits, how tos that work well please help me out because I cant seam to find any

point the photosensors down and tweak the code if necessary.

hey does this line follower use d PID control algorithm?

?

jwatte · « **Reply #24 on:** January 21, 2013, 12:03:45 PM »

I don't know about that particular high school project, but in general, you use a PID controller for a continuous channel of control. For example, if you have an encoder for motor speed, and want to drive motor PWM to make the motor rotate at a particular speed, PID can implement that. Similarly, if you have an analog input for how far left/right a line is, you can create a PID controller to output the "turn" signal to follow the line straight. (You can also create various kinds of oscillation by not setting the P,I,D values right :-)

However, "line followers" typically also need to make decisions, like whether to go left or right at an intersection; those kinds of decisions cannot use PID controllers, because that's a higher-level logic function.

[ those kinds of decisions cannot use PID controllers]
bt line follower robots can also use PID controllers to know how far they are from d line and take a turn proportional to that....
maybe u r right n m wrng (as ur a expert roboticist n m jus a beginner) bt this is what ive learned from member tutorials.....
