3pi robot - Line Following

This is my 3pi robot going around a small track. It's running the standard PID line following program with calibrated values. I'm preparing to enter the Eastern Canada Robot Games competition (2009).

Just as a note, it hit my foot at the beginning, I was trying to hold down the track.

Later: I won the competition.

can u send me the PId constants ?

@karandex

int power_difference = proportional/3 + integral/50000 + derivative*4/1;

It could still use some tweaking, but it works out pretty good at 255 motor speed.

I modified the line following to go 100% 100% of the time

Can post what values you get after calibration? I'm trying to find, but no luck :(

hey, i need to build one, how can you make it go so fast even in curves? are u using servos??

[sosodude]

that is pretty fast
