This year 2073 used a USB webcam on our bot to track the balls. It was implemented to assist the driver with alignment to balls when they were obstructed from his view or just too far away to easily line up.
We won the Inspiration in Control Award at both Regionals we attended because of it.

Cool -- we actually did the same thing, and fed back to the driver station which balls were detected in the field of view, and also their distance + offset angle from our collector. Seemed to work pretty well but when we were out on the field we didn't use the autonomous control for it just because of the nature of defensive and high-speed gameplay. Unfortunately we didn't win a Controls award at either of our regionals. Would love to compare code though!

Did it work something like this?

I would prefer not to hijack this thread, but here is a short description of what we did. If you would like to discuss this further, please PM me or maybe I can create a new thread.

Yes and no. We never feed video back to the driver. We just used the value of "x center" of the ball to steer the robot whenever the driver needed assistance. One button on the steering wheel overrode the wheel position and replaced it with the "((image x center - ball x center value) * k)". "k" was a gain value used to bring the error value to a useful level to steer the robot.

All image acquisition and processing were done on a PCDuino on-board the robot. None of the network traffic for this crossed the WiFi network, it all stayed local to the robot.

I think this would be a great thread. It would be cool to know if any other teams tried it and are willing to share how they did it.
