Launch Files

• Audience: developers
• Level: beginner

ROS programs are made up of a bunch of small modules called Nodes. To make a ROS program like openag_brain, you configure a set of nodes with a .launch XML file.

openag_brain contains default launch files designed for the Food Computer 2.

Launching ROS at startup

Launching ROS at startup can be accomplished in a couple different ways:

• Configure a Linux service to run ROS at startup
• Use a Docker container for ROS and have Docker manage running at startup.

openag_brain will configure a service automatically when installed globally. When installing with Docker, docker-compose handles restarting across reboots.

Launching ROS in background

To run ros in the background, you can use a program like screen.
