Thanks! We enter targeting mode by pressing and holding a button on our joystick, you actually see the transition in the video from the robot right side view as it turns around from looking at us, we just turn around so we generally face the target, hold the button and go! I would have like to include better video of the transitioning but we had limited space since it was raining outside all day!

I believe in this video we are using 320x240, though we have tested and driven using 640x480. With 640x480 we get around 5-7 FPS, using 320x240 the FPS counter jumps around between 7-14 FPS, though generally around 8 FPS.



As to how we did this, Im not sure what technical info my team would prefer me to divulge. But I can say that we looked at the image processing capabilities of the cRio, then we read the rules:

Custom circuits may be used to indirectly affect the robot outputs by providing enhanced sensor feedback to the cRIO-FRC to allow it to more effectively control the ROBOT.
And then drew a logical conclusion.
