Setup

The following setup instructions are intended for Ubuntu 18.04. You can find more detailed information on the setup in Ubuntu 18.04 and other OSs with the link at the end of this section.

MATLAB R2023a

Install MATLAB R2023a with the following toolboxes:

• Matlab Coder
• Parallel Computing Toolbox
• Statistics and Machine Learning Toolbox
• ROS Toolbox

System Requirements for MATLAB ROS Toolbox

In our priority-based trajectory planning, vehicles communicate using the MATLAB ROS toolbox. Their custom messages are compiled with the MATLAB built-in function ros2genmsg(), for which you must have Python software, CMake software, and a C++ compiler for your platform (ROS Toolbox Requirements). For MATLAB R2023a

• Python
  1. Install Python 3.8
     sudo apt install python3.8 python3.8-venv python3.8-dev
  2. Setup Python in the MATLAB command window:
     pyenv(Version="3.8")
  3. If Matlab cannot find Python, try:
     pyenv(Version=/usr/bin/python3.8)
• C++ compiler
  1. Install GCC and G++ Version 7.x+
     sudo apt install gcc-7 g++-7
  2. Set them as the default compiler
     sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 70 --slave /usr/bin/g++ g++ /usr/bin/g++-7
  3. Setup the compiler in the MATLAB command window:
     mex -setup

Setup Details

More detailed information including troubleshooting can be found here.

Experiments

1. Execute startup.m to open the project
   • Compilation of graph_search_mex should fail
   • Compilation of lanelet2_interface should fail
   • Compilation of priority_queue should succeed
2. Execute main.m to run an experiment
   • Select the environment Simulation
   • Select the control strategy pb non-coop
   • Push the Start button to start the experiment
   • Options that does not work in this setup are:
     • Environments: CPM Lab, Unified Lab API
     • Checkbox: use C++
     • Scenario: Lanelet2, Lab Default
