Just added “scanning” option to the CTS module. Once defined the classes of colors you want to track you can trigger a scanning for one of the color classes just issuing one command. The CTS module will control the pan and tilt servos scanning for that color, once founded will return the position of the camera as servo pulse width in micro seconds. Based on the servo used we can find the angle for pan and tilt.
Beside just scanning for a color this can be used to find for example the position of the CTS module relative to 2 or more items of known colors when we know the distance between them.
