I need your Guidance.
I am using Pololu QTR-8RC (all 8 sensors) sensor for line follower robot. I have tested my robot for line width of 15-20mm in which line just fits in the distance between two sensors. I used the Position reading of the sensor to calculate my Error value and then obtained the motor speeds using PID calculation.
But now I want my robot to follow the Line of width of 30-35mm. Here, in the desired position, the central three sensors are on the line at the same time.
So, in this scenario, Will the position reading from the sensor be accurate and Can I use this reading to calculate my error and Motor Speeds?.
