I'm going on with ezb camera experimentation. I have experimented color or multicolor tracking . The x and y servos actually track the colored object and put it near the screen center, but they go on indefinitely moving around the screen center, with wide oscillations. I adjusted the x and y "increment steps" in the configurazion window, reducing them to "1", but the oscillations are still there. It seems like the servos move too much , i.e. the gain of this closed loop system is too high, making it unstable .A typical event in closed-loop systems. I adjusted the small-large setting but it has no effect on oscillations, simply it stops tracking when not properly adjusted. I also tried adjusting the grid lines, making the center zone narrow , hoping this could reduce the oscillation amplitude, but moving these lines seems to have no effect. I don't understand what are they for. I found no tutorial explaining in detail what's their use. What more can I do ? Using this tracking to control my robot , I'd have a Parkinsonian robot !

Have you actually clicked the check box to "use grid lines" in the camera control settings (below servo tracking check box)? By default I believe this is unchecked...
OK, Richard, this is the right way to make it work. You solved my problem. Sometimes I sink into a glass of water !... I didn't notice the box to enable grid lines !.... Tutorials don't help much . One must click everywhere and see what happens. Oscillations are now 2 or 3 only, then it stabilizes. It's hard work. Continuous adjustment of grid lines, brightness, contrast, etc. is needed, depending on room light, surrounding objects, etc...to achieve good results.
Tutorial's don't help much..? confused
You didn't notice the box to enable grid lines because you didn't follow the tutorials lol...my goodness.
Hi, newagetomy, tutorials do help, but often don't say everything one should know ! I haven't read anywhere about grid lines .
