Hi Ahmed,
To connect to your Linux machine running ROS 2 simulation from MATLAB, you can use the MATLAB ROS Toolbox. The ROS Toolbox provides a set of functions and tools for interacting with ROS from MATLAB.
Here are the general steps to establish a connection between MATLAB and your Linux machine:
1. Install the MATLAB ROS Toolbox: Make sure you have the ROS Toolbox installed in your MATLAB environment. You can check if it is installed by typing `ros` in the MATLAB Command Window. If it is not installed, you can install it using the MATLAB Add-Ons menu or the MATLAB command `add-ons`.
2. Set up ROS environment variables: On your Linux machine, ensure that the necessary ROS environment variables are set. You can do this by sourcing the appropriate setup file for your ROS distribution. For example, for ROS 2 Foxy Fitzroy, you can run the following command in a terminal:
source /opt/ros/foxy/setup.bash
3. Connect MATLAB to the ROS master: In MATLAB, use the `rosinit` function to connect to the ROS master running on your Linux machine. You need to provide the IP address or hostname of your Linux machine as an argument. For example:
rosinit('http://<linux_machine_ip_address>')
4. Verify the connection: After running `rosinit`, MATLAB should establish a connection to the ROS master. You can verify the connection by running `rosnode list` in the MATLAB Command Window. It should display the list of active ROS nodes on your Linux machine.
Once the connection is established, you can use the ROS Toolbox functions to interact with the ROS topics, services, and parameters on your Linux machine. For example, you can use `rostopic` functions to subscribe to topics and receive data in MATLAB for further analysis.
Note that you need to ensure that your Linux machine and MATLAB are on the same network and can communicate with each other. Make sure that any firewalls or network configurations are properly set up to allow communication between the two.
For more detailed information and examples, you can refer to the MATLAB documentation on ROS Toolbox: ROS Documentation
I hope this helps you establish a connection between MATLAB and your Linux machine running the ROS 2 simulation.
