CMUcam2 Vision Sensor

Good self-contained module, $200, user guide here (pdf)

Need to get a new module or find if previous camera can be still found. Experiments:

1. detect red game ball
2. track red game ball moving horizontally across the camera's field of view
   
3. connect camera servo controllers (built-in), so that the camera can tilt up and down.
4. track red game ball moving from floor level to straight above the robot

Ok, ordered the sensor from Acroname Robotics
Total price with UPS Ground delivery $208

Ok, got the camera and gave it to Andrew. Tested the camera with the included Java GUI application - connected the camera through the serial port, the picture goes through, can pick color and can track the middle of the region. I made a backup copy of the software on my laptop.
