Hi Ivan, When you create NH nh_private("~"), it makes a handle that references the nodelet manager's private namespace, not that of the individual nodelet. If possible you should use the [nodelet::Nodelet::]getPrivateNodeHandle() method to find the proper namespace. If you have a non-private NH for your nodelet already, you could also use something like `NodeHandle private_nh(public_nh, "~")` - Ken
