After following this procedure, we can build the package using catkin_make and if the build is successful, we can generate the shared object libnodelet_hello_world.so file, which is actually a plugin.
The first step in running nodelets is to start the nodelet manager. A nodelet manager is a C++ executable program, which will listen to the ROS services and dynamically load nodelets. We can run a standalone manager or can embed it within a running node.
The following commands can start the nodelet manager:
- Start roscore
$roscore
- Start the nodelet manager using the following command
$ rosrun nodelet nodelet manager __name:=nodelet_manager
If the nodelet manager runs successfully, we will get a message ...
