I think the problem might be your ROS package path not pointing to your catkin workspace correctly.

CHeck the ROS_PACKAGE_PATH environment variable (used by ROS to locate packages) echo $ROS_PACKAGE_PATH

it should point out to two locations, one of them should be your catkin workspace.

@hasauino

h@hercules:~/robot_operating_system/first_workspace/catkin_ws$ echo $ROS_PACKAGE_PATH /opt/ros/kinetic/share

It shows only one path. What as I missing here?

[hasauino]

You can add your workspace to $ROS_PACKAGE_PATH environment variable by sourcing the setup file inside devel folder of your workspace:

source ~/robot_operating_system/first_workspace/catkin_ws/devel/setup.bash

you may also add this line to the bashrc file so this step happens automatically everytime you open a terminal:

echo "source ~/robot_operating_system/first_workspace/catkin_ws/devel/setup.bash" >> ~/.bashrc

source ~/.bashrc

@hasauino Thank you.

Now it is working.
