So I've only been messing with ROS for about 16 hours now but I am
trying to get my smart arm working.  I downloaded the smart arm
controller and all of its dependencies.  I have it installed and it runs
partially.  The motors for single motor joints (the base, gripper left +
right, and wrist rotate) work but the double motor joints (the elbow and
the shoulder) don't start.  I do get error messages out but I have been
working on this for 5 hours and I can't figure out what is happening.

NODES
  /
    joint_position_controller
(ax12_controller_core/controller_manager.py)
    smart_arm_controller_spawner
(ax12_controller_core/controller_spawner.py)
