RoboRealm can write values to NetworkTables. There is an example on this web page:
http://wpilib.screenstepslive.com/s/...client-pc-side
that demonstrates writing a robot-side and laptop-side NetworkTables program to communicate data. If you assume that RoboRealm is the laptop-side program you can use the robot-side example here.
There's some information about using RoboRealm at the bottom of the web page.
