Jared and Tom, thanks for a great talk!

Audio on this is perfectly fine, and paired with the slides on a second monitor I was able to get everything out of the presentation.

This was some pretty awesome stuff. I was hoping to have the team work on a new co-processor based vision system over the offseason, and I can see this presentation influencing a lot of it. There was really something in that presentation for everybody; they managed to cover the basics while still focusing on things like predictive vision and how to actually determine the real world coordinates of the goal. Another home run talk by the cheesy poofs; I can't wait to see what they come out with next year.

I flew in late on Wednesday, so I'm sad I missed this and I haven't heard the audio yet. However, the presentation slides are quite excellent!

I know that in 254's current tracker you're using an external processor and aiming for maximum performance for your image processing -- but I'm curious if you've tested the current hardware with a lesser performing camera setup. For example, on the RoboRIO I estimate our image processing code is 320x240 @ 10fps with ~100ms latency (haven't measured lately, but I seem to recall that's what I got when I did measure). How much does your turret tracking degrade with that kind of lower performance? Or does the latency compensation and high quality construction of the turret compensate for that?

It would work fine. The fact that the goal is static, and you can estimate your robot's movement VERY accurately over a few hundred milliseconds, combine to mean that you can do really well even with lots of latency and limited resolution.

Has anyone found the magical archive of the talks? I was really looking forward to getting to see this one and karthik's
Luckily, you guys have promised getting it online, but if someone could have a link to all of them that would be amazing. There dosen't seem to be anything on the FIRST champs website.
