Hi Troy, I don't know if you've succeed in configuring Embodiment to control the robot, using ImplicationLinks, but here http://www.opencog.org/wiki/Embodiment#Language_Comprehension you can find a documentation about the Language Comprehension module, which was integrated into opencog a few days ago. In the Reference and Command resolution sections you will find how a specific command can be implemented to be fired by a simple English sentence. If you have any question, please feel free to send an email to the list or post it on the #opencog channel at irc.freenode.net.
