Native installation of the MRS UAV System

Native installation

1. Install the Robot Operating System (Noetic):

curl https://ctu-mrs.github.io/ppa-stable/add_ros_ppa.sh | bash
sudo apt install ros-noetic-desktop-full

2. Configure your ROS environment according to http://wiki.ros.org/ROS/Tutorials/InstallingandConfiguringROSEnvironment

3. Add the stable PPA into your apt-get repository:

curl https://ctu-mrs.github.io/ppa-stable/add_ppa.sh | bash

• Special instructions for the MRS System developers

  • Instead of the stable PPA, you can add the unstable PPA, for which the packages are build immediatelly after being pushed to master.
  • If you have both PPAs, the unstable has a priority.
  • Beware! The unstable PPA might be internally inconsistent, buggy and dangerous!

4. Install the MRS UAV System:

sudo apt install ros-noetic-mrs-uav-system-full

5. Start the example Gazebo simulation session:

roscd mrs_uav_gazebo_simulation/tmux/one_drone
./start.sh

How to update the MRS UAV System

Issue the following command to update the MRS UAV System:

sudo apt update && rosdep update && sudo apt upgrade --with-new-pkgs --allow-downgrades

What does it do?

• sudo apt update will refresh the available debian packages from the archives.
• rosdep update will refresh the rosdep depedency tree >
• sudo apt upgrade will download the new versions of packages.
  • --with-new-pkgs will ensure that if new dependency appears for an already installed package, it will be installed as well.
  • --allow-downgrades will allow to downgrade a package version. This happens when installing our forks of official ROS packages.
