I am on the first tutorial on the Connecting to the Bus. I've reached the step to launch the file but it is giving me the following error:

ERROR: cannot launch node of type [dynamixel_controllers/controller_manager.py]: dynamixel_controllers
ROS path [0]=/opt/ros/indigo/share/ros
ROS path [1]=/home/rohit/catkin_ws/src
ROS path [2]=/opt/ros/indigo/share
ROS path [3]=/opt/ros/indigo/stacks

I got the launch file from this page I have sourced the environment and the ROS_PACKAGE_PATH is also correct to my knowledge. I am using ROS Indigo on Ubuntu 14.04. I did an apt-get for the dynamixel packages, sourced the environment. Any help will be much appreciated, thank you.

Please add how you setup your environment, what platform this is and how you installed the dynamixel_* packages.

Which packages did you install? What does rospack find dynamixel_controllers return?

I checked my /opt/ros/indigo/share folder and it currently has dynamixel_motor, driver, controllers, msgs. rospack find returns:

/opt/ros/indigo/share/dynamixel_controllers
