Hi-Speed cameras for robot development

[Bennett548]

Has anyone out there used a high speed camera for robot development or testing? I'm not talking about using slow motion on your camera phone, I mean something that captures 500+ frames per second (fps) that allows you to see something you couldn't see at normal speed.

Here are some of the times in the past that I would have liked to have one:
2009: see how well traction control systems worked on the regolith
2012: watch the wheels compress the basketballs to see what effect the compression has on wheel slip.
2013: watch the shooter wheels interact with the discs to judge what wheels to use.
2014: watch the impact of our ball puncher to find out the best puncher plate shape for better accuracy
2015: canburglars. all we see in a 240fps video is a blur, higher speed was needed

There are a few less expensive hi-speed cameras on the market:
$5,495: Edgertronic
$532: FPS1000 (kickstarter, none delivered so far)

If the second one turns out to work well I think it would be a good investment for a robotics team, especially if a school's physics department is willing to split the cost.
