The roboRIO does have a pull-up, but it may not have been strong enough for your sensor. I didn't look for this one, but for the very similar QS18VN6LV the leakage current spec suggests it won't work on the roboRIO without an additional pull-up (though the one I tested did seem to work plugged in direct).
