hi guys, i am working on a robot which is supposed to move and when sees a red bricket stops and turns to another way. i am using CMUcam. my questin is: how can i teach the robot to avoid red colors. i mean for example:

IF b>x THEN

FOR a=1 TO 30
PULSOUT 14, 1000
PULSOUT 15, 500
PAUSE 100
NEXT

ENDIF

where x is a minimum value of red color or something. basicly what is the number x?

Isn't there documentation on the CMUCam that tells how it 'identifies' a 'blob' of a particular color?

no, i looked and found nothing useful.

Look at the code examples at the bottom of the page for the CMUcam.
