My class and I are following the curriculum for VEX IQ and are attempting to do the simple line tracking. We cannot get our IQ's to track a line at all. We are using track line left and the robot just keeps turning left. It doesn't matter if we start completely over the line or over the left edge of the line, still just turns left. We have tried getting the greyscale values for white and black, adding them together and dividing by 2 to set the first dropdown box as well as changed the turn values to 50 & 40. Still doesn't work. Please tell me what I am missing here?

I spent last week helping an end-user with their two-robot visual line tracking system. As far as systems like these go, this one’s pretty simple: just two robots, one backlit conveyor, one camera and basically one product. The entire codebase comes in well under a thousand lines. We had issues that were hard to solve despite the simplicity. What follows is my process while debugging several common visual tracking errors.
version: visual line tracking is hard. -
