Here is a video I threw together one day using a go pro on our robot.

The video itself, although you might not realize it, is from 4 different matches and 2 competitions. I do recommend finding a nice and sturdy place for it, you wouldn't want anything to happen to it. Also, make sure your memory cards are full
. If you use it, try to get as many different shots as possible. It's not fun thinking of neat shot the day after your last competition...
