Clone the repository and update the submodules.
git submodule update --init --recursive
Change into the docker directory and build the docker image. This may take a while.
cd docker
./build.sh
Run the docker, everything from here will be executed inside it.
./run.sh
Follow the instructions given at the start of the docker
colcon build
source colcon_build/install/setup.bash
ros2 run freespace_planner simulation.py
src/freespace_planner/ros2/scripts/sim_config/sim_config.yml
The SCENARIO_NAME controls which map to use.
ALL_VISIBLE decides if the environment is previously known.
src/freespace_planner/library/config/config.yml
src/freespace_planner/library/config/params.yml
Here, all the library params can be adjusted. Some can also be set during runtime in the Gui.
If you receive the error:
Could not initialize GLFW!
Verify that the DISPLAY variable is set to the same value inside the docker as outside with echo $DISPLAYand set it with e.g. export DISPLAY=:1
You are welcome to contribute to every part of this project. Given the fact, that the python part is already planned to be replaced by C++, it would be more beneficial to contribute to the C++ part :)
