At the kickoff Dave Lavery demonstrated the camera tracking the green target and aiming a laser pointer just below it. The code was developed by Neil Rosenberg, FRC Engineering Manager and he has provided the code for that demo as well as a program to demonstrate the camera tracking multiple targets simultaneously. There is also a video that shows the operation of the camera with the code.
