I doubt the LM317 would be capable of putting out the amount of current required for OP's test bed. The cRio alone is rated for 800mA, which is half the LM317's nominal current output. Add a sidedar and some motors, and you're well over the 317's 1.5A rating.
Here's some pics of my conversion. I've done a couple others, and they all work very well.

And if in the end the students are inspired and more of the public becomes aware of the program, and people gain more appreciation for engineering, how can that not be a good thing? - dlavery [more]
