Important: first launch the launch file (multirobot_navigation_slam_toolbox.launch.py), and then run the exploration logic in a separate terminal (explore_map2)
First:
ros2 launch multi_robot_navigation multirobot_navigation_slam_toolbox.launch.pyThen in a separate terminal window:
ros2 run multi_robot_explore explore_map2I'm not sure, but if stuff isn't working out for you, you could try installing the Python package shapely.
First make sure that your system is up-to-date:
sudo apt updateIf it is needed, you can upgrade:
sudo apt upgradeThen install dependency:
sudo apt install python3-shapelyDon't forget to build (colcon build) and source the bash file (source install/setup.bash)!
