The most direct way to do this is to configure the I/O board as normal, then simply read the analogs you want on the robot. You don't mention a language, but all have access to the FT values via the DriverStation object or library.

On the robot, do the math to combine them into the appropriate control values e.g. speed= (x+y+z)/3, or whatever you need.
