Regarding The cRio

[biojae]

As far as communications go, the second ethernet port on the cRio (one that communicates to FMS) can be used to talk to the second cRio.

<R68> All outputs from sensors, custom circuits and additional electronics shall connect to only
A. other custom circuits, or the following:
B. additional COTS electronics, or
C. input ports on the Digital Sidecar, or
D. input ports on the Analog Breakout, or
E. the RS-232 DB-9 serial port on the cRIO-FRC, or
F. the Ethernet bus connected to Port 2 of the cRIO-FRC,

Emphasis mine.

Emphasis mine.

Its also probably possible to hook up another microcontroller as a Digital I/O

Which is correct, but if you have an ethernet port on your microcontroller (or 2nd cRio) why wouldn't you want to get 1 or more megabytes per second throughput?

Going through GPIO is going to be slower then ethernet.

If I have an ethernet port on the microcontroller (not a 2nd cRio) where would the camera plug in if the 2nd port is used up? Not using it on the microcontroller, its too much for it

According to this Q&A post : http://forums.usfirst.org/showthread.php?t=14423

"<R68> Says the Ethernet bus connected to Port 2 of the cRIO-FRC may be used.

Does this mean that a network switch may be used to communicate between devices on the bus as long as the command signals originate from the cRIO-FRC?"

Yes.

Now keep in mind that rules change from year to year, these are only this year's.

A network switch! Never thought of that

If I recall correctly theres a rule somewhere restricting the amount you can spend on a single electronic components. I think it was $400, so that excludes the cRio (which you can get one at a discount from NI for something like $1500 I think).

[Radical Pi]

I don't think you can count an extra cRIO as KOP component. Also, would the cost be considered 750 or 1400 dollars (the offseason rate vs full)

this sounds like a better investment: its cheaper (way cheaper) and its C++

Though the little battery may have to go (even though its current output is inconsequential)

rule <R01> and <r40>

<R40> The only legal primary source of electrical energy on the ROBOT during the competition is one MK ES17-12 12VDC non-spillable lead acid battery, OR one EnerSys NP 18-12 battery, as provided in the 2010 KOP. Teams may use other equivalent 12V batteries during development, testing and practice MATCHES. However, during competition MATCHES only one MK ES17-12 battery OR one EnerSys NP 18-12 battery can be used on the ROBOT.

"• Power input range of 6V to 24VDC"

But the battery is a 12v, so it would work

The Cmos Battery? Hmm... that does seem to be an issue.
Well, I guess we can cross the roboard <rb-100 OR rb-110> off the list

Has a battery, not legal. Extra Crio costs too much. Whats wrong with the Gumstix and Beagleboard proposed on the other thread?

Never really looked into it


edit: you can always get teh battery plug thing at radio shack and rig it up to the power distribution board


Looked into the beagle, I like it, but its purpose is too general, the other link has robotics in mind, so it has pwm out puts and stuff, but this does not. Will ahve a meeting with Mentors, Programmers and electronics
