How to import all of the ROS messages from a remote machine to your machine (for visualization, for example).
Step-by-step guide
- Sometimes, you can't have a direct connection to the machine running the ROS Master you need access to...
- You could ssh into it, and see nothing OR
- You can export the ROS Master to your Machine.
- You can do this in three easy steps. (Or, you can write an alias for it! More on that later).
To Export the ROS Master to your local machine:
$ export ROS_MASTER_URI=http://<ip of machine running ROS Master>:11311 $ export ROS_IP=<ip of machine running ROS Master> $ source ~/.bashrc
If you want to write an alias, do the following on your local machine
$ sudo nano ~/.bash_aliases # at the bottom of the .bash_aliases file, append the following alias <name of macnine running ROS Master>='export ROS_MASTER_URI=http://<ip of machine running ROS Master>:11311 && export ROS_IP=<ip of machine running ROS Master>' # REMEMBER: you MUST update the IP of the machine running the ROS Master in this alias each time it changes (about once per day)
