The new 4 slot cRIO-FRCII

Considering the fact that the cRio runs a relatively lightweight OS, you should have no performance issues at all. Honestly, I find it hard for any team to even come close to 50% ram usage. As my programming mentor put it: "FIRST gave us a Lamborghini as the main control system".

true, and with the new wireless system, camera streaming is no longer a problem. so i don think there is really any reason to upgrade.

I have failed to gather any information regarding the "4-slot cRIO-FRCII". Has anyone found any information on it at all? Has anyone gotten a brochure or flyer from National Instruments at their booth?

Most likely, they will not release information just yet because these cRIO's are FRC specific, so I doubt information will be on the public website. Because of this, they will probably release information after beta testing is complete or as beta testing occurs.

Remember. Just 4 seasons ago (2008), we used an 8-bit microcontroller getting control update packets at ~40Hz measuring in bytes, and running at a system frequency of 4MHz. That power level was only just slightly restricting the best teams.

Our current system (2009-2011) is a 32-bit PowerPC processor, capable of receiving control packets at ~6MB/s, running at a system frequency of 400MHz.

Its the comparison of the old system like being a Camaro or Corvette, more than enough power for 99% of people, but those top few race teams need a Ferrari instead. The cRIO is WAY overpowered for our uses. You don't buy a Ferrari to fetch the groceries and take the kids to soccer practice.

Our team is pretty set on getting a new 4-slot mostly because we've been wanting a second unit for a little while, and this is a slightly cheaper way to go. It will definitely be going on competition robots since it is smaller and a bit lighter. It's also a bit more powerful, but as pointed out, that's hardly a consideration as they're way overpowered already (until you start running LabVIEW... another thing we might look into changing). The old 8-slot will migrate around on old robots, practice robots and the like, and we also shouldn't forget that we have two perfectly good IFI systems lying around.

There is an existing thread on this:
http://www.chiefdelphi.com/forums/sh...ad.php?t=94889
It includes pictures(the real new CRIO isnt listed on the NI website since it is custom for first), and discussion on the tech specs on the new CRIO as obtained from the NI people at Championship. The major new info we have is when it will be sold.

I believe this is the base model of the the FRC-II, and the 9074 was the base model of the eight slot.

A clarification to other posts -- the controllers are essentially OEM specialized versions of a standard NI cRIO. They are not custom designed. The custom parts are the PD and breakouts.

Greg,

Any knowledge on whether the cRIO-FRC II will interface with the 2011 FMS? Our cRIO bit it at Peachtree, and we have at least one more date with the FMS this year.

[Greg McKaskle]

There are no known incompatibilities.

Have you sent the 8-slot in for repair? I'm not sure what it bit, but it can most likely be fixed.

I got very, very excited about this when it was announced.

We are planning on getting one in the fall. Although the extended RAM is something we don't need, having a smaller base will be much nicer. Plus one of our 2 current C-Rios got a little wet in transit and although it works, it hasn't been up to par with the dry one.

All I can also say is that made the decision for us we're upgrading to a trailer from just using tarps.
