Package Summary

ROSspawn allows to start, stop, and monitor ROS nodes remotely. Opposed to roslaunch it does not read files with configurations to load, but rather it exposes services and topics to inform about available ROS nodes (i.e. binaries in appropriate folders) which can then be started and stopped.

The Basics

This ROS package provides a node that can start and stop other nodes. It is intended to be instructed from another node to launch specific nodes, for example by rosspawn_gui.

rosspawn does not try to be another roslaunch. Rather it is meant to provide tools for a different use case. During development, nodes are started and stopped frequently while people are working on the node. With roslaunch, this often means either starting and stopping larger ensembles, or getting a hold on the controlling machine's terminal for a specific node. rosspawn launches the nodes by itself, usually instructed by its companion application rosspawn_gui from any of the developer's machine. It resembles the way Fawkes plugins are loaded and unloaded. While nodes are running, they are monitored by rosspawn and status changes are announced. Other developers see if a node has been stopped by someone else.

rosspawn is mostly a proof of concept at this stage. It lacks some important features in comparison to roslaunch:

Since the number of binaries grows big very fast, rosspawn allows to create a module file which contains the names of the modules which should be announced by rosspawn.

This is a proof of concept implementation and probably not useful in its current state. Comments and patches welcome.

Usage

Run bin/rosspawn. Then run rosspawn_gui and click on any node name to get it started or stopped. Usually no modifications are necessary to the nodes. Nodes which are started without using rosspawn are currently not recognized.
