Component Dimensions

[Kevin Sevcik]

Mirroring a thread from ChiefDelphi:
Size and Weight of Components

I don't care very much at all about what magic happens inside to make the robots go -- but I have to find a place to stick all of this stuff on our new and old machines.

Can one of the beta test teams please share information about the overall dimensions and weight of each of the components?

To which I'll add that it doesn't have to be incredibly precise. Rounding up to the nearest ounce and half inch or so would probably be fine for right now.

Indeed - a good clear photo of each component would be helpful as well, so we can understand a little about what kind of clearances might be necessary at the sides for wires etc.

Thanks,
Don

Here's a clear photo of the bench test setup we did.

The next best thing to having a ruler in the pic is that the "Digital Sidecar" (Smaller of the two blue boxes, is the same size as a 3"x5" card, because that's what we had on the board for the first week because we didn't have the real thing

Note that most of these parts do NOT have silk screen legends on them, or the correct color coded terminals. This made our initial assembly tricky, but the final devices will be fully labled and color coded.

Intentionally missing from this setup are Spike modules for pneumatics etc. That's because you'll only need one for the compressor. Up to 8 solenoids will be able to be driven DIRECTLY from the cRIO without spikes.

Oh, and the Big Flashy orange Light is back, but not with the dumb relay module required back in 2007. It's driven directly from the Digital Sidecar.

Also, note that there is no backup battery or charging circuit... Both are eliminated by in the Power Distribution Module.

Sorry for the delay but I misplaced the data.
The weight of each component:

NI cRIO Chassis 27.8 oz
Power Distribution Block 27.7 oz
cRIO I/O w/bumpers 32.4 oz
SideCar w/cable 12.2 oz
Camera 6.2 oz
Wireless Access Point 5.4 oz

My estimate of the difference in weight between the old and new systems:
Approximately 5 lbs

Does anyone have weights and dimensions for the old IFI system? I think that the 5 lb estimate for increased weight is a bit high since the sum of the weights that are listed is about 5 pounds.

We posted our results in the thread linked above. Here they are for reference:

New Control System:
cRio with 5 modules 1740gm
cRio with no modules 910gm
9201 module 130gm
9403 module 130gm
9472 module 130gm
analog bumper 25gm
pneumatics bumper 25gm
Distribution Block 727gm
Digital Side Car 95gm
Digital Side Car Cable 190gm
Radio 135gm

IFI:

Robot Controller: 330 grams
2007 or 2008 radio: 175 grams
Backup Battery: 165 grams
Spike: 50 grams
Breaker panel: 120 grams
Rockwell Power Distribution Block: 160 grams
40 amp breaker panel: 300 grams

I estimated the difference as 2-3 pounds extra, depending on whether you used 2 40 amp breaker panels, and whether we will be allowed to remove unused cRIO modules, among other things. With the new system, you don't need a backup battery, or spikes to control your solenoids, so you do save weight there.

As far a size, practically, It didn't really take up any more space on our robot then the other one. Things are different shapes, so there may be some robots it won't fit in, and other robots where it will fit better. If you're designing a robot around it, I don't think it will be a problem.
