2015-08-26 04:21:21 -0500 asked a question dynamixel_controllers problem

Hello,I am trying to follow the Dynamixel motor tutorials. I receive and error when trying to run the command roslaunch my_dynamixel_tutorial start_controller.launch.

self.diagnostics_pub = rospy.Publisher('/diagnostics', DiagnosticArray) [INFO] [WallTime: 1440579977.825270] pan_tilt_port: Pinging motor IDs 1 through 25... [ERROR] [WallTime: 1440579979.830732] Exception thrown while getting attributes for motor 1 - 360 [ERROR] [WallTime: 1440579979.839960] Exception thrown while getting attributes for motor 1 - 360 [ERROR] [WallTime: 1440579979.849312] Exception thrown while getting attributes for motor 1 - 360 [ERROR] [WallTime: 1440579979.858010] Exception thrown while getting attributes for motor 1 - 360 [ERROR] [WallTime: 1440579979.866353] Exception thrown while getting attributes for motor 1 - 360 [INFO] [WallTime: 1440579979.868803] pan_tilt_port: Found 0 motors , initialization complete. /opt/ros/indigo/lib/dynamixel_controllers/controller_manager.py:126: SyntaxWarning: The publisher should be created with an explicit keyword argument 'queue_size'. Please see http://wiki.ros.org/rospy/Overview/Pu... for more information. self.diagnostics_pub = rospy.Publisher('/diagnostics', DiagnosticArray)

I have the correct baud rate set for the motor as well as the correct motor IDs,and when i try to launch roslaunch my_dynamixel_tutorial controller_manager.launch. i got errors [INFO] [WallTime: 1440580069.779623] pan_tilt_port controller_spawner: waiting for controller_manager dxl_manager to startup in global namespace... [INFO] [WallTime: 1440580069.786608] pan_tilt_port controller_spawner: All services are up, spawning controllers... [ERROR] [WallTime: 1440580069.824340] Initialization failed.

Also, a Warning states showed up in the terminal where i had open the start_controller.launch file [WARN] [WallTime: 1440580069.822682] The specified motor id is not connected and responding. [WARN] [WallTime: 1440580069.823288] Available ids: [] [WARN] [WallTime: 1440580069.823701] Specified id: 1
