ROS Toolbox System Requirements

ROS or ROS 2 Node Deployment and Custom Messages

To generate custom messages for ROS or ROS 2, or deploy ROS or ROS 2 nodes from MATLAB® or Simulink® software, you must build the necessary ROS or ROS 2 packages. To build these packages, you must have Python® software, CMake software, and a C++ compiler for your platform. To generate and deploy ROS or ROS 2 nodes from MATLAB or Simulink, you must also have a MATLAB Coder™ or Simulink Coder license respectively. To generate and deploy CUDA® optimized ROS or ROS 2, you must have a GPU Coder™ license.

Note

The nodes in MATLAB and Simulink software can communicate with ROS or ROS 2 nodes in ROS or ROS 2 distributions that are not supported in MATLAB and Simulink, only if the message definitions are the same.

Configure Python Environment

To connect to ROS networks with the rosinit function, you must install and set up the required version of Python. After you install and setup the required version of Python, follow these steps to configure it for use with ROS Toolbox.

Starting in R2022b

  • On the Home tab in the Environment section of the MATLAB toolstrip, click Preferences.

  • Select ROS Toolbox, click the Open ROS Toolbox Preferences button, and specify the path to the Python executable that you installed in the previous step.

  • Click Recreate Python Environment.

    Default view of ROS Toolbox Preferences dialog box. Browse to navigate to the parent directory of python executable. Click Recreate Python Environment.

Prior to R2022b

  • To check your Python version, use the pyenv function. For example,

    pyenv
    ans = 
      PythonEnvironment with properties:
    
              Version: "3.9"
           Executable: "C:\Python39\python.exe"
              Library: "C:\Python39\python39.dll"
                 Home: "C:\Python39"
               Status: NotLoaded
        ExecutionMode: InProcess
  • If your Python interpreter is set to a different version, restart MATLAB and set the version with pyenv.

    pyenv(Version="3.9")

Starting in MATLAB R2022a

Since R2022a, ROS Toolbox supports the Noetic Ninjemys distribution for ROS and the Foxy Fitzroy distribution for ROS 2.
