ROS Custom Message Support

Create ROS custom messages

You can create your own ROS custom messages and use them in MATLAB® and Simulink® with ROS networks to transmit information. You can also replace the built-in messages with new or custom definitions. To learn the requirements for generating custom messages, see ROS Custom Message Support.

For ROS 2, use ros2genmsg with your custom message packages.
