Sure. but you will need some way of measuring the arm's position ie an encoder or if its rotation is limited another potentiometer on the robots arm wired to a analog input on the CRIO. Then in code you can compare the value of the potentiometer with the position of the arm and figuer out what direction to move. a simple way to do this is to subtract the two potentiometers (desired position - actual position) the result is how far off you are and the sign represtent the direction you need to go.
