Re: Why the sudden burst of code postings?
I agree wholeheartedly. There are many many times I've looked at a veteran team's code (Thanks 254 and 2481!) and leveraged the ideas (hopefully making them better along the way). Our team has been...

Re: IP Cameras
Axis cameras are pretty standard. For vision processing, i'd recommend the M1011 over the M1013 - the 1013 has some auto-image-adjust features which you cannot turn off and can wreak havoc with image...

Re: Arduino programming tool.
Nifty! I will have to check this out when I get home. Definitely looks like a low cost way to get into model-based software development!
I believe Simulink also supports building for Arduino...

Re: FRC 2170 Stronghold code release
Nifty, thanks for sharing!
Looks like you were using a coprocessor and Grip? What sort of coprocessor was it, and how did you like working with it?

Re: Single vs Multiple Speed Gearbox
Very much depends on the game, your strategy, and how effectively your driver can use both speeds.
For Stronghold, our bot had two-speed gearboxes on the drivetrain. We mostly stayed in low gear,...
