So, using the servo camera example, we can get a rough green hue but can't get it to move. If you can we need a way to move the camera, and get a better hue for both green and pink, for green we are using 100-140 hue 0-255 sat 0-255 luma. We do not currently have a set for pink.

Move as in with servos? in Labview?

Are you using the locate colored object example or the servo camera example or none of those?

The servo camera example needs a watchdog, so if you add that, it should work for tracking.

I need more information to properly answer your question:confused: :)

In addition to what Booksy said, you need to have a jumper on the digital sidecar next to the PWM port of any servo. Learned that the hard way.

Ok... but, somebody could tell me how I include or setup the WDT in LV?????
I have included in the Block Diagram but the servos didn't work :(

Are you asking how to add the watchdog? Where is the Block Diagram included? I don't understand...

If you are using the two color servo example, it already feeds the watchdog. It assumes the servos are on channel 9 and 10 of module 4, and the green and pink default values should work pretty well. If you tweak them, you may not want to change them as much as you have. 100-140 may work for hue depending on the white settings of your camera, but they seem high. I generally think of 75 as green. I've seen it go over 100 in sunlight. Setting the lower bound of saturation and luminance full open will allow in all shades of gray and objects with even a slight green tint, which when your lighting is tinted green will be everywhere.
