Basic Rigging: Rotation of Object A influences the Location of Object B

How would I go about this - I want to rotate object A to move object B on a certain axis…?
I’m guessing it has something to do with Transform Constraint but I can’t figure it out.

Thanks!

You could use drivers. RMB on a parameter and select Add Driver. Then set up in the Graph Editor set to Drivers http://wiki.blender.org/index.php/Doc:2.6/Manual/Animation/Basics/Drivers
See the attached driver.blend file.
You can also use the Transformation constraint. See the attached transform.blend file

Rotate the empty to move the monkey head along the x axis
