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?
