Thanks for the quick response. First, I have told the robot to move forward until it detects a black line then stop. It does this perfectly and is very nearly centered on the black line. Then, when it gets to the line following part of the program, it makes the first left turn until it sees the white area and stops and will not continue. Originally, I had the turn speed at 50 percent power, but I changed it to 100 hoping that maybe it was just moving to slow for me to see.

I think that it might be a problem with the while loop, seeing how it only does the first step. I have tried multiple conditional statements in order to get the loop to work, but it always stops after the first turn. Hitachi Cambridge Interactive Whiteboard Drivers there.

There are three programs provided for the Line Follower: The LineFollow2 program is a basic 'Two State' line follower that uses a simple 'zig-zag' method of line.

About the threshold value, I am using the Robot Virtual Worlds program, so I do not know of a way to check the values. 50 has been working so far. Thank you so much for your help! Planet X In Bible Prophecy Pdf. Lacey Wed Aug 07, 2013 1:07 pm.
