Robotics

So I'm making a robot follow a line using an IR sensor.

This is the main part of the program, every other function is listed in their own voids.

I can't test it out because the robots aren't available yet. Are there any like "OH SHIT NIGGER WHAT ARE YOU DOING" errors?

PROGRAM:



void GoForward() //Self Explainatory
{
    mav(0,300);
    mav(3,300);
}

void SeekLeft()
{
    mav(0,-200);
    mav(3,200);
    sleep(0.8);
}

void SeekRight()
{
    mav(0,200);
    mav(3,-200);
    sleep(0.8);
}

void ReturnLeft()
{
    SeekRight();
}



void ReturnRight()//SeekLeft, SeekRight, ReturnLeft, and ReturnRight are used to correct the robot if it goes off of the line
{
    SeekLeft();
}

void FinalAttempt() //The robot flails around to the left endlessly
{
    mav(0,500);
    mav(3,-500);
}

void FollowLine()
{
    while(1) //Makes the program always happen
{
GoForward(); //It moves forward until
}   
if(analog(3)<180) //The sensor shows a value of <180 (light) meaning it has moved off of the tape, then it will
{
    SeekLeft(); //Turn to the left very briefly
    if(analog(3)>180)//If the sensor shows a value of >180 (dark) meaning it is back on the tape, it will
    {
        printf("Line found; Curving to the left.\n"); //Display this on the screen
        return; //go back to main, which makes it go forward again
    }
    ReturnLeft();//If turning right fails, it will center itself again, and then
    SeekRight();
    if(analog(3)>180)
    {
        printf("Line found; Curving to the Right.\n");
        return; //Same thing as before. However, if it fails to detect the line a second time after turning,

    }
    ReturnRight(); //It centers itself, and then
    FinalAttempt(); //Flails around trying to find some sort of line
    if(analog(3)>180)
    {
        printf("Line Found on Final Attempt. WARNING: Robot is probably following line in opposite direction.\n");
        return;
    }
    ao(); //If that fails, which shouldn't happen, then it will just shut off.
    printf("Error: Line lost. Write a better program!/n");
}
}

int main()
{
    FollowLine(); //Runs the FollowLine program. Just a way of making things simple in the main.
}

Your compiler went full retard.

I asked if anything was wrong with it, not for you to click "compile" and c/p the results.

Dayumn.

why are you doing one line functions that send you to another function to actually do the work. fucking stupid.

void GoForward() //Self Explainatory[sic]
See kids, this is what happens to your brain when you don't use the [code] tags.

Are there any like "OH SHIT NIGGER WHAT ARE YOU DOING" errors?
Yes. Yes, there are.
I'd list some of them, but you should probably be writing this as a state machine anyway.

    printf("Error: Line lost. Write a better program!/n");
At least you have a sense of humour.

SHERMAN'S LAGOON   BY JIM TOOMEY

Megan : "I SAW THIS ADVERTISED ON TV AND I HAD TO GET ONE."

Sherman : "A ROBOT?"

Megan : "NOT JUST ANY ROBOT. IT'S A GENIE 4000. IT'S GOING TO TAKE MY PLACE WHILE I'M GONE.

WITH THE GENIE 4000, YOU CAN GO OUT OF TOWN, AND WHEN YOU RETURN, ALL THE CHORES HAVE BEEN DONE.

OKAY, I'M LEAVING NOW. SEE YOU IN A WEEK."

Sherman : "HAVE FUN, MEGAN."

Silence

Sherman : "I'M CURIOUS TO SEE HOW THIS THING WORKS."

Robot : "BEEP BZZZZT!

EMPTY THE DISHWASHER."

Hawthorne : "I THINK IT'S TALKING TO YOU."
