I wrote you at your email, but I guess you did not get it.  
Yes I am using Teensy to run the robot arm and roboclaw controllers.

I finished the project, I am able to make the robot pick the blobs one by one. Thanks a lot,

I am trying to move into OPENCV. Have experience?  
I cant get the video to work,

I took an example that uses a video file and tried to replace that with streaming webcam video but no luck.

this line is the trouble  
opencv = new OpenCV(this, video);  
The error says" Width(0) and height (0) cannot be \<=0"

I will make a new topic for all to see.
