You can download USB Webcam support packages for MATLAB, which should let you stream Webcam data right into MATLAB on your PC: http://www.mathworks.com/hardware-support/matlab-webcam.html

As for the robot servos, that depends on how they are controlled. What are the servos connected to -- an Arduino or something?

Perfect!

So, you can look at Image Analyst's color tracking demo and wrap that around the USB Webcam and Arduino support packages for sensor input and actuator output, respectively.

Have fun :)

track_color_in_video.zip

See my attached demo where I find and track a green Sharpie marker in a video. You'd just pull the frame from your video feed instead of from the video file.

yes i know but i had r2009 version and not running m-file,so that i asked, but know i install r2014 and i run ur m file and its running.But I need a code that activates the camera and identify red spots and moves the arm on them. It is possible to make them in a m-file ??? or if it is possible to add some code in m-file you sent ??? Your file does not turn on the camera and not communicating with servo.... i hope to understanding what i looking for.

Thanks for ur time !!.
