⚠️ Attention please: This package is no longer maintained!!!This is an old package that is no longer maintained. The new version of the UAV Core is located here. This repository will be erased soon
Required OS is Ubuntu 20.04 LTS 64-bit or their flavors that can install ROS Noetic. The suggested variant of OS installation is dual boot instead of virtualization that can be slow and can not handle well the simulation GUI. We use Gitman to manage the repository submodules. The repository are supposed to be compiled by catkin tools.
The install.sh script will add the following to your .bashrc:
source /opt/ros/noetic/setup.bash

source $HOME/git/uav_core/miscellaneous/shell_additions/shell_additions.sh
provide some useful command line aliases (git, catkin, cd) and some neccessary shell functions (wait* commands for simulation).
All the environment variables define a particular configuration of a UAV (through launch files). The variables apply mostly to real hardware. They allow us to make the core universal without the need of hardcoding configurations for a particular UAV, but only for a UAV type. In a simulation, they are mostly overloaded in each tmuxinator session.
One of the features of our shell_additions.sh that might be intrusive is our cd alias.
Our cd is capable of automatically traversing from locations that have been symlinked somewhere, to the linked location.
This is especially useful if you (like us) clone git repositories under a specific location, e.g., ~/git/my_repository and then link them to catkin workspaces, e.g., ~/project2_workspace/src/my_repository.
When you call
cd ~/git/my_repositoryour alias will put you in
user@machine:~/project2_workspace/src/my_repository$A symlink map (stored in /tmp/symlink_array.sh) for all your workspaces is built automatically after boot (after the first start of the terminal) by a detached tmux session using the silversearcher-ag utility.
Only the workspaces in the environment variable
export ROS_WORKSPACES="~/mrs_workspace ~/modules_workspace ~/workspace ~/project2_workspace"are considered.
The ROS_WORKSPACES variable is added during the installation of MRS UAV system since that is where we set up the workspaces for you.
