Also, if you have a reentrant clone VI and need to edit it, press ctl-m, which is a shortcut for Operate >> Change to ... Mode. This lets you go between run and edit mode for any VI. Clones default to Run Mode.

Glad to help out other FRC'ers :-)

And thanks for that tip. That's MUCH easier than what we had to do

Thank you all for the response! Extremely helpful. I will try this out and post how it turns out.

I'm sorry but even after following your instructions and pictures to the dot it doesn't seem to be working. Also the code you attached is trying to access the default WPI VIs that are on my computer. Can you save the modifications you made to the WPI Camera VIs into the project as new VIs and repost it?

Glad you guys got it all working! Just a piece of advice from a former driver, though – you will probably not be looking at your driver station laptop nearly as much as you think you will. Driving is stressful and dangerous and it's hard to tear your eyes away from the field and down to your computer.

That's my experience anyway. Just something to keep in mind!

Thanks for the advice! I was the driver for our team for 2 years, and I can concur, however , with how little visibility there is on the field this year, it will be difficult to see what's in front of your robot at times (e.g. a boulder behind the drawbridge).

We have tested the latency on the camera over wifi from the robot (not through the FMS, so it might vary), and it isn't that bad. We calculated it to be only about 90-100ms lag. We had our driver drive it a bit ONLY looking at the webcam image, and he said he could drive it just fine.

I will post the VIs. I will try to get them out before the end of the week (school, work, robotics, etc )

Also, I double-checked the rules, and we're not allowed to use port 1181. We have to use a port somewhere in between 5800 and 5810 (per R60)
