@labkit it is part of the SDK but not installed on the kernel - on you voxl2 please run the following:
sudo apt-get install voxl-ros2-foxy
sudo apt-get install voxl-microdds-agent
sudo apt-get install voxl-mpa-to-ros2
voxl-configure-mpa-to-ros2
Once this is done you should be ready to use ros2 by running source /opt/ros/foxy/setup.bash as well as export ROS_HOME=/opt/ros/foxy
Hope this helps. Also ensure that for the voxl-configure-mpa-to-ros2 line you have an active internet connection on the voxl2 as this requires some pip installs.
Thanks!
