The issue was that I was not using the controller files correctly. Of the the three files that were posted above, I used the last two.

The following file is called controllers.yaml:

controller_list:
  - name: arm
    action_ns: follow_joint_trajectory
    type: FollowJointTrajectory
    default: true
    joints:
      - plat_joint
      - shoulder_joint
      - forearm_joint
      - wrist_joint

Is utilized when the .launch file is run while the controllers1.yaml file is run by ros_controllers.launch:

Publish all joint states -----------------------------------

joint_state_controller: type: joint_state_controller/JointStateController publish_rate: 100 # Position Controllers ---------------------------------------

Control all joints

arm: type: effort_controllers/JointTrajectoryController joints: - plat_joint - shoulder_joint - forearm_joint - wrist_joint

state_publish_rate: 100

gains: plat_joint: {p: 100, i: 0.0, d: 0} shoulder_joint: {p: 100, i: 0.0, d: 0} forearm_joint: {p: 100, i: 0.0, d: 0} wrist_joint: {p: 100, i: 0.0, d: 0}

The names of the controllers above ('arm' and 'joint_state_controller') must be referenced in the file that launches this yaml file (ros_controllers.launch).
