Title: Line Following Sensor Array - i need some help on it
Post by: airman00 on November 26, 2007, 06:49:36 PM

On my line following robot I have the following arrangement of sensors:

                       0                    0
                               000


What basically happens is that the robot looks ahead with the two front sensors for sharp turns.

HOWEVER, the robot mistakes sharp turns for a break in the line with this array.


I was thinking of doing this

                    000
            0                  0

So once the front three sensors lose the line the back sensors will see if a sharp turn exists or not.

Any suggestions on a better sensor arrangement?

You may want to go for this arangement:

0        0
   0  0
     0
