Depencies & ROS2 Intallation

You can review the installros.sh file under isaacsim_launcher/isaacsim_ws directory. That shellscript prepared according to ROS2 Humble documentation.

    sh <path the isaacsim_launcher directory>/isaacsim_ws/installros.sh

Update .bashrc

Add the following block at the end of .bashrc. You have to pay attention about the "isaacsim_launcherDirectory", it has to point the isaacsim_launcher directory. This following block just example.

	isaacsim_launcherDirectory=/home/${USER}/isaacsim_launcher/
	###################
	### EXPORTS
	export ROS_DOMAIN_ID=0
	export FASTRTPS_DEFAULT_PROFILES_FILE=${isaacsim_launcherDirectory}/isaacsim_ws/fastdds.xml
	export _colcon_cd_root=/opt/ros/humble/
	export ISAACSIM_PATH="${HOME}/.local/share/ov/pkg/isaac-sim-4.1.0"
	export ISAACSIM_PYTHON_EXE="${ISAACSIM_PATH}/python.sh"
	### EXPORTS
	###################
	###################
	### SOURCES
	source /opt/ros/humble/setup.bash
	source ${isaacsim_launcherDirectory}/isaacsim_ws/install/setup.bash
	source /usr/share/colcon_cd/function/colcon_cd.sh
	source /usr/share/colcon_argcomplete/hook/colcon-argcomplete.bash
	### SOURCES
	###################

Miniconda3

    https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh (for x64)
    sh <Miniconda3-latest-Linux-x86_64>@Downloads directory
    accept eula, and no for init
    conda config --set auto_activate_base false

Finally, add the following block at the end of .bashrc if only if doesn't exists!

    # >>> conda initialize >>>
    # !! Contents within this block are managed by 'conda init' !!
    __conda_setup="$('${HOME}/miniconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
    if [ $? -eq 0 ]; then
        eval "$__conda_setup"
    else
        if [ -f "${HOME}/miniconda3/etc/profile.d/conda.sh" ]; then
            . "${HOME}/miniconda3/etc/profile.d/conda.sh"
        else
            export PATH="${HOME}/miniconda3/bin:$PATH"
        fi
    fi
    unset __conda_setup
    # <<< conda initialize <<<

IsaacLab

    cd ${isaacsim_launcherDirectory}/IsaacLab/
    ln -s ${ISAACSIM_PATH} _isaac_sim
    ./isaaclab.sh --conda
