Thanks, and awesome job.

This is a targeting reticle as such where the spheres are calibrated to the actual balls size of it's apex and place to land. When we had our manipulator working it shot 27 feet. So there are 27 segments in the path align each measured at one foot.
This video can hopefully illustrate how these work a little better. Our strategy was to look for robots that could catch and use this system to deliver balls to them over the truss. That and being able to score with the aid of the apex marking.
If you watch the video you may notice the path align moves... this moved when the robot moves, but I had that demo not connected so it moved 1 fps by default... the idea there is when connected and fully moving it almost looks like the robot is riding on train tracks and the rails width are 25 inches apart (i.e. ball diameter). This helps predict where the ball is going to land easier for the eyes to anticipate hitting the mark for a motion shot.
Thanks for the feedback... these compositing tools are highly configurable and should be able to be used in future games as well.
There is one other note worth mentioning... on the m1013 we stream 600x800 30 fps using h264 running 1.5 or less mbps, with 4-5 frames of latency (that is only one frame of latency more than using mjpeg with the benefit of low bandwidth).
