ROS in Simulink
ROS Toolbox enables you to connect to ROS and ROS 2 in Simulink and send messages over the network. See Get Started with ROS in Simulink.
You can also generate and deploy code to a target system. For an advanced example on creating a standalone ROS node, see Generate a Standalone ROS Node from Simulink.
To run, stop, or check the status of deployed ROS nodes available on a ROS device,
use the MATLAB® functions listed. Create a connection to a ROS device using
|Blank Message||Create blank message using specified message type|
|Call Service||Call service in ROS network|
|Current Time||Retrieve current ROS time or system time|
|Get Parameter||Get values from ROS parameter server|
|Header Assignment||Update fields of ROS message header|
|Publish||Send messages to ROS network|
|Read Data||Play back data from log file|
|Read Image||Extract image from ROS Image message|
|Read Scan||Extract scan data from ROS or ROS 2 laser scan message|
|Read Point Cloud||Extract point cloud from ROS PointCloud2 message|
|Set Parameter||Set values on ROS parameter server|
|Subscribe||Receive messages from ROS network|
|Write Image||Write image data to a ROS or ROS 2 message|
|Write Point Cloud||Write point cloud data to a ROS or ROS 2 message|
