Access ROS networks and messages using MATLAB®

ROS shares information using messages. Messages are a simple data structure for sharing data. To receive or subscribe to a message, use rossubscriber. To send or publish a message use rospublisher. See Exchange Data with ROS Publishers and Subscribers for more information on sending messages.

ROS services and actions enable users to perform tasks. Services use request-response communication to gather information and trigger callback functions in the ROS network. Actions can be used to trigger tasks or goals and receive feedback during operation of these tasks.
