Hello, I am following the tutorial for dynamixel_contollers as posted on

When I run "", in the console where I run controller_manager.launch show: Incoming trajectory joints do not match the joints of the controller. Exception in your execute callback: not all arguments converted during string formatting.

Also when I run the start_meta_controller before, at the end it appears: all processes on machine have died, roslaunch will exit shutting down processing monitor complete.

Thank you very much for your attention.

I have already solved it, the fault was in the line: goal.trajectory.joint_names. You have to remove: +char.

How about trying to do with Dynamixel-Workbench? This is official package to support Dynamixel by ROBOTIS. You can take more information when you connect Dynamixel to ROS.
