ROS Network Access in MATLAB
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.
